feat: dogfood content allocation pattern on autonomous-dev's own files (Stream A)

[akaszubski]

Summary

Apply the content allocation pattern (proven in realign) to autonomous-dev's own CLAUDE.md, PROJECT.md, and memory directory. Dogfood the pattern before extending the plugin to ship it for other repos.

Implementation Approach

1. Refactor CLAUDE.md (144 → ≤100 lines): remove Session Analytics SQL block (duplicates global CLAUDE.md), move long Commands list to docs/COMMANDS.md if not already there, keep rules + paths + pointers + canonical link to CONTENT_ALLOCATION.md.
2. Refactor .claude/PROJECT.md (366 → ≤150 lines): consolidate purpose/architecture/scope; move operational content (periodic maintenance tables, batch sequences) to docs/RUNBOOK.md.
3. Sweep autonomous-dev memory dir (18 files → ~12) using concrete criteria:
   • <500 bytes AND not active finding → delete (stub)
   • >3KB AND reads-like-doc → move to docs/
   • Content is just "[rule] — see CLAUDE.md" → delete
   • session_*_outcomes.md >7 days old → delete
   • RESOLVED/DONE/SUPERSEDED markers → delete
4. Write docs/development/CONTENT_ALLOCATION.md in autonomous-dev's repo (manually authored, mirrors realign's). This becomes the canonical template in Issue Command Discoverability Broken: 21 advertised, only 8 exist #3.
5. Update MEMORY.md index entries to reflect deletes/moves; keep entries ≤150 chars.

Acceptance Criteria

• CLAUDE.md ≤100 lines
• .claude/PROJECT.md ≤150 lines
• MEMORY.md ≤200 lines (fits load window)
• docs/development/CONTENT_ALLOCATION.md exists and matches realign's pattern
• Memory file count reduced; no rule duplicates of new CLAUDE.md remain
• All existing autonomous-dev tests pass (pytest --tb=short -q)
• git diff review: no behaviour changes, only content reorganisation

Notes

This is Stream A of the broader retrofit plan (see .claude/plans/content-allocation-retrofit.md). Stream B (plugin extension) is Issues #2-#4 and depends on this work landing first.

Implemented in caa7154 — content allocation pattern dogfooded on autonomous-dev's own files. CLAUDE.md 144→62, PROJECT.md 366→115, MEMORY.md 135→139 (all within budget), memory dir 13→12, new docs/development/CONTENT_ALLOCATION.md + docs/RUNBOOK.md, doc-congruence tests passing 24/24.
