feat: session recovery toolset (orphan detector + /recover)

Reconstructs session logs from Claude Code transcripts when a session
crashes or is closed before /save. Two entry points:

- /recover <uuid|latest> : manual, Claude-reviewed reconstruction
- detect_orphaned_sessions.py : scheduled scan that auto-builds logs for
  substantive, unsaved, not-yet-recovered transcripts (banner-marked
  RECOVERED-UNVERIFIED), commits them, and posts a #bot-alerts FYI.

recover_session.py is the shared engine: Python extracts the verbatim
command/config/reference timeline; Ollama drafts prose-only narrative.
Machine-local ledger (.claude/state/) prevents reprocessing. Reviewed:
git add scoped to own files, ledger written only after successful push,
per-uuid idempotency, --max cap for unattended runs.
