feat: v2.0.4 "Deep Reference" — cognitive reasoning engine + 10 bug fixes

New features:
- deep_reference tool (#22): 8-stage cognitive reasoning pipeline with FSRS-6
  trust scoring, intent classification (FactCheck/Timeline/RootCause/Comparison/
  Synthesis), spreading activation expansion, temporal supersession, trust-weighted
  contradiction analysis, relation assessment, dream insight integration, and
  algorithmic reasoning chain generation — all without calling an LLM
- cross_reference (#23): backward-compatible alias for deep_reference
- retrieval_mode parameter on search (precise/balanced/exhaustive)
- get_batch action on memory tool (up to 20 IDs per call)
- Token budget raised from 10K to 100K on search + session_context
- Dates (createdAt/updatedAt) on all search results and session_context lines

Bug fixes (GitHub Issue #25 — all 10 resolved):
- state_transitions empty: wired record_memory_access into strengthen_batch
- chain/bridges no storage fallback: added with edge deduplication
- knowledge_edges dead schema: documented as deprecated
- insights not persisted from dream: wired save_insight after generation
- find_duplicates threshold dropped: serde alias fix
- search min_retention ignored: serde aliases for snake_case params
- intention time triggers null: removed dead trigger_at embedding
- changelog missing dreams: added get_dream_history + event integration
- phantom Related IDs: clarified message text
- fsrs_cards empty: documented as harmless dead schema

Security hardening:
- HTTP transport CORS: permissive() → localhost-only
- Auth token panic guard: &token[..8] → safe min(8) slice
- UTF-8 boundary fix: floor_char_boundary on content truncation
- All unwrap() removed from HTTP transport (unwrap_or_else fallback)
- Dream memory_count capped at 500 (prevents O(N²) hang)
- Dormant state threshold aligned (0.3 → 0.4)

Stats: 23 tools, 758 tests, 0 failures, 0 warnings, 0 unwraps in production
