feat: index Codex sessions alongside Claude Code with source tagging

Add `source` column to sessions and messages ('claude' | 'codex'). Discover and parse Codex JSONL files from ~/.codex/sessions/, mapping Codex thread/item structures to the same schema (messages, tool_calls, tool_results, subagents). Move DB to ~/.obelisk/ with legacy migration. Add rebuild-to-temp-then-swap for safe full rebuilds. On the app side: source filter toggle, collapsible untitled session fold, configurable codexDir in Settings, and a dev script. Update SKILL.md and query helpers to expose source fields and accept source filter opt.
