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/.
