feat(chat): Redis rate limiter, persistent presence, PostgreSQL full-text search
- Rewrite chat rate limiter with Redis sliding window (sorted sets) and
automatic in-memory fallback when Redis is unavailable
- Add ChatPresenceService with Redis-backed online/offline/heartbeat
tracking (2min TTL), integrated into Hub register/unregister
- Add migration 113: tsvector column with GIN index and auto-update
trigger on messages table for full-text search
- Update Search repository method to use ts_rank ordering instead of ILIKE
- Wire Redis client into chat WebSocket setup in router.go
- Add comprehensive tests: rate limiter, presence, 100-user concurrent benchmark
