feat: evolve retrieval layer with content_type, memory FTS, forget(), and recap references

Extract schema DDL into scripts/schema.sql. Add content_type and is_meta columns to messages for transcript control-plane filtering. Introduce FTS5-backed memory recall with safe tokenization, memory soft-delete via forget() through the renamed --attune runtime, and anchors on memory records. Expand query helpers (includeMeta, thread opts, overview project-path awareness). Add per-card recap retrieval and writing references under references/recap/.

 a memory is wrong, outdated, or should be replaced, the agent can archive or

 The executable SQLite schema lives in `scripts/schema.sql`; `references/schema.md`
 is the human/agent explanation of that contract.
 The design is progressive disclosure with guardrails: the main skill keeps the
 core contract and high-risk pitfalls visible, while longer recipes and the full
 schema stay out of the first prompt until the agent needs them.
 The optional recap references are only for the explicit `/obelisk recap` intent;
 they are not part of the ordinary retrieval path. `references/recap/overview.md`
 drives a card-by-card loop: read one card's retrieval pattern, gather that
 card's evidence, read its writing reference, update the JSON, then continue.
 This keeps schema, taste, and query planning from competing in one large prompt.

 The index rebuilds incrementally — only new or modified JSONL files are re-parsed.
 When the optional app is running, it is the active indexer: it watches Claude
 project files, builds in a worker thread, writes `__app_heartbeat__` plus
 `__app_last_successful_build__` into `index_state`, and the skill-side lazy
 build skips work only while both markers are fresh.

 ## Intent Routing
 Obelisk supports a small intent prefix layer after `/obelisk`. This is for
 output intent, not retrieval architecture.
 | Intent | Description | Reference |
 |---|---|---|
 | `recap [target]` | Generate weekly/monthly recap card content for app handoff or share-style output. | `references/recap/overview.md` |
 Routing rules:
 1. If the first word is `recap`, read `references/recap/overview.md` before the
   first query. Everything after `recap` is the recap target.
   Common app-generated prompts include `/obelisk recap this week`,
   `/obelisk recap last week`, `/obelisk recap this month`, and
   `/obelisk recap last month`; interpret these as natural period targets
   relative to the current date and timezone.
 2. `recap` does not create a separate retrieval layer. It still uses
   `overview()`, `memories()`, helpers, and `sql()` only when needed.
 3. Follow the overview's card-by-card sequence. Each card has its own retrieval
   pattern and writing file; retrieve that card's evidence, read that card's
   writing file, update the JSON, then move to the next card. Do not preload all
   recap references before the current card is written.
 4. If the first word is not `recap`, do not load
   `references/recap/overview.md`. Continue with Query Routing below. Do not
   infer recap from broad requests for weekly/monthly summaries, charts,
   rankings, shareable cards, or playlist-style metaphors.
 ## Query Routing
 Before writing a query, classify the task. Progressive disclosure is useful, but
 skipping the relevant reference usually costs extra query rounds.

 - Read `references/retrieval-semantics.md` before multi-step retrieval, scoped project/file/session searches, or synthesis/conclusion/history questions. It defines the query design frame.
 - Read `references/schema.md` before raw `sql()` unless the needed table/column relationship is already explicit here. Do this before running the SQL, not after a missing-column error. Do not start with raw SQL for broad synthesis unless helpers cannot express the needed aggregation or join.
 - Read `references/pitfalls.md` after an error or when helper fields, FTS syntax, aliases, or row shapes are unclear.

 # Obelisk Recap Overview
 Use this only when the first word after `/obelisk` is `recap`. Everything after
 `recap` is the target period or style hint.
 ## Highest Priority: Phase Loop
 This workflow is sequential. Do not preload all recap files. Do not gather all
 evidence first and write all cards at the end.
 Follow this loop exactly:
 1. Resolve the target period from the user's phrase.
 2. Run only a tiny orientation pass such as `overview({ limit: 6 })`.
 3. For Card 1, read `pattern1-cover.md`.
 4. Retrieve only Card 1 evidence.
 5. Read `writing1-cover.md`.
 6. Update/write the JSON for Card 1 now.
 7. Only after the JSON is updated, move to Card 2 and repeat.
 Card order:
 | card | retrieve | write |
 |---|---|---|
 | 1 cover | `pattern1-cover.md` | `writing1-cover.md` |
 | 2 thinking | `pattern2-thinking.md` | `writing2-thinking.md` |
 | 3 vibe | `pattern3-vibe.md` | `writing3-vibe.md` |
 | 4 workflow | `pattern4-workflow.md` | `writing4-workflow.md` |
 | 5 closing | `pattern5-closing.md` | `writing5-closing.md` |
 The per-card files own retrieval details, JSON field duties, and card-specific
 taste. Do not move those concerns back into this file.
 ## Period Targets
 - `this week`, `last week`: calendar week in the user's runtime timezone.
 - `this month`, `last month`: calendar month in the user's runtime timezone.
 Do not infer timezone from examples, UTC suffixes, or file timestamps when
 runtime/session timezone is available.
 ## Overall Deck Taste
 This is a Spotify Wrapped-like set of personal share cards: concise, designed,
 slightly playful, and built to make the user's work feel seen.
 Do not criticize the user. Do not scold, diagnose, rank their personality, or
 turn friction into a performance review.
 Use designed English chrome where it feels like card UI: week/month labels,
 archetype labels, compact stats, verdict seals, and signoffs. Preserve the
 user's own language for prompts, quotes, catchphrases, and reactions. This is
 not a translation task.
 The deck should feel like a small artifact from someone who noticed the week,
 not a report generated from a database.
 ## Archetypes
 Choose one dominant archetype from the period's dominant attention, not from the
 current recap-generation session.
 | archetype | when it fits | tone baseline |
 |---|---|---|
 | `architect` | structure, boundaries, schema, systems | matter-of-fact structural pride |
 | `debugger` | symptoms, false positives, root-cause loops | wry and bug-comfortable |
 | `shipper` | dense implementation cadence | energetic but not breathless |
 | `curator` | organization, memory, docs, refinement | reflective and precise |
 | `director` | workflows, subagents, orchestration | observant from a slight remove |
 | `cartographer` | moving boundaries and redrawing maps | patient and surveyor-like |
 | `wanderer` | many projects without one center | gentle, exploratory |
 If two fit, pick the one that describes what the user spent more thinking time
 on, not what shipped.

 Use the period from `overview.md`. Start from `overview({ limit: 6 })`, then
 look at in-period sessions, summaries, memories, and any obvious project scope.
 If the user asked for a project, keep that scope; otherwise prefer the current
 project only when the evidence makes it the clear center.

 - persona: which archetype best matches the user's attention;
 - source sessions and memories used by this cover claim;
 - activity: weekly day intensities or monthly day intensities when supported;
 - footer: compact public metric such as sessions, messages, or tokens.
 Avoid:
 - a claim that lists three topics;
 - an archetype chosen from the recap-generation session itself;
 - footer caveats like excluded projects, exact SQL filters, or long session names;
 - making the cover a workflow metric when the week was really about a decision.

 # Card 2 Thinking Retrieval
 Goal: find turning points. This card is not a project timeline and not an implementation log. It is the record of what changed in the user's mind.
 Retrieve 3-6 turns. A turn needs both sides:
 - the user question, friction, doubt, or request that started the turn;
 - the later decision, reframing, finding, or constraint that replaced the earlier
  state.
 Useful searches:
 - user questions in the period: "为什么", "是不是", "怎么", "我觉得", "不应该";
 - places where the user corrected the direction and then approved a new frame;
 - summaries that name decisions, followed by `context()` or `thread()` for the
  user's actual words;
 - memory records only as hints; raw session evidence must provide the prompt and
  turn.
 Prefer helpers first. If you need custom SQL for message windows or user-turn
 counts, read `references/schema.md` before writing the SQL.
 Do not use workflow names, feature names, or agent task labels as prompts when
 the user had their own wording. Do not use counts, "5 rounds", "13 agents", or
 implementation effort as turns unless that count is the turn itself.

 # Card 3 Vibe Retrieval
 Goal: find small human signals in visible user messages. Vibe is not a correction log, not bracketed runtime text, and not a psychological profile.
 Look for:
 - catchphrases and repeated tiny reactions;
 - unusually blunt praise or rejection;
 - late-night disbelief, jokes, or rituals;
 - one quotable sentence that captures the period's character.
 Only count visible user messages. Helper APIs omit meta by default, but custom
 SQL for phrase counts must filter user text with `COALESCE(m.is_meta,0)=0` and
 `m.content_type='text'`. Do not count tool results, injected command envelopes,
 UI labels, or bracketed runtime strings.
 Useful retrieval:
 - targeted phrase counts after you notice a likely catchphrase;
 - `thread(sessionId)` around high-energy moments;
 - `search()` for exact phrases, then `context()` for timing;
 - a bounded SQL count only after reading `references/schema.md`.

 # Card 4 Workflow Retrieval
 Goal: find actual workflow runs and how the user received them. Card 4 is about
 orchestration as experienced by the user, not an agent performance table.
 Workflow rows have their own `workflows.timestamp`. During this card's retrieval,
 call `workflows({ project: projectLike, after, before })` before concluding the
 period had zero workflows.
 Prefer helpers first. If you need custom SQL for workflow joins, timestamps, or
 message reactions, read `references/schema.md` before writing the SQL.
 Do not derive workflow counts only from `sessions({ after, before })`: long
 sessions can start before the period and still contain workflow runs inside the
 period. Do not scope workflow lookup by exact `project_path`; nested cwd values
 can belong to the same Claude project slug.
 For each candidate workflow:
 - get the actual workflow_name from `workflows()` or `workflowTree()`;
 - collect run id, timestamp, project, agent count, and compact result for stats
  and evidence only;
 - search the parent session for the user message immediately following the workflow completion;
 - use that user reaction as `items[].reaction`.
 Rank rows by the strength of the user reaction, not by agent count, workflow
 size, duration, or implementation importance. A small workflow with "完美" is a
 better row than a large workflow with no visible response.
 Do not use architecture topics, memory-system milestones, app modules, or recap
 feature work as workflow rows unless they are actual workflow_name values.
 Do not make a row for a workflow with no visible user reaction; keep it only in
 `stats`, `metrics`, or `evidence`.

 # Card 5 Closing Retrieval
 Goal: close with a small personal receipt. Use the same period and source scope
 as the recap, or explicitly record a wider metric in `evidence`.
 Retrieve:
 - one consistent metric that can stand alone, such as streak, active days,
  sessions, messages, or workflows;
 - one or two compact receipts;
 - most said phrase, only if a real repeated user phrase is supported;
 - signoff material from the period's mood, not a second summary.
 For phrase counts, count only non-meta visible user text. For streaks and active
 days, define whether the scope is all Obelisk data, the current project, or the
 selected evidence sessions. Keep the scope consistent with the cover footer
 unless the evidence explicitly says otherwise.
 Prefer helpers first. If you need custom SQL for phrase counts, active days, or
 streaks, read `references/schema.md` before writing the SQL.

 - `title`: persona label, usually `The Architect`, `The Debugger`, etc.
 - `claim`: one plain claim; not a topic list, project inventory, colon-led

 #### `forget(record)`
 Archive a human-approved memory record. Use it when the user says a memory is
 outdated, wrong, or should be forgotten. It is available only in scripts run
 with `runtime.mjs --attune`.
 `forget()` requires a precise memory ID. Do not pass a query string and let the
 helper choose. If the ID is unknown, first use a normal `--query` script with
 `memories()` to identify candidates. If exactly one candidate clearly matches
 the user's request, the request is approval to archive it. If multiple memories
 could match, ask the user which one to forget.
 | Param | Type | Description |

 | `record.id` | `string` | Memory record ID to archive |
 | `record.reason` | `string` | Required reason for audit and future management views |
 `forget()` sets `deleted_at` and `deleted_reason`. It does not delete the
 markdown file at `path`. Active recall helpers omit archived memories.
 **Returns:** `{ id, deleted_at, deleted_reason }`, or the same fields plus
 `already_deleted: true` if the record had already been forgotten.
 ```js
 return forget({
  id: 'mem-20260610-example',
  reason: 'Outdated by newer project guidance.',
 });
 ```
 #### Memory Mutation Approval
 Agents may decide whether to use, ignore, or verify memory in a single answer
 without approval. Approval is required only for persistent memory mutations.
 When the user explicitly says a memory is wrong, outdated, should be forgotten,
 or should say something else, that utterance is approval to mutate the exact
 matching memory. If multiple memories could match, ask the user to choose.
 Updating is not an in-place edit. Archive the old record with `forget()`, then
 write and register a replacement markdown file with `remember()` under the same
 approval.
