feat(odin): Phase 2a read-only agentic assistant + tool-trace UI

- agentic chat loop (max 6 round-trips, budget re-checked between iterations)
  over 10 read-only, permission-delegated tools in src/services/ai-tools.ts
- persist assistant tool trace in ai_chat_messages.content_json (+ migration)
- consulted-tools chips in OdinThread; header now shows month spend only
  (budget cap hidden from the UI, server-side 402 guard unchanged)
- seed: ai.use permission; Settings exposes the ai permission module
- docs: REVIEW consolidation; deployment-guide.md superseded by docs/release.md
