feat(intelligence): complete Phase 2-3 migration to Rust

Phase 2 - Core Engines:
- Heartbeat Engine: Periodic proactive checks with quiet hours support
- Context Compactor: Token estimation and message summarization
  - CJK character handling (1.5 tokens per char)
  - Rule-based summary generation

Phase 3 - Advanced Features:
- Reflection Engine: Pattern analysis and improvement suggestions
- Agent Identity: SOUL.md/AGENTS.md/USER.md management
  - Proposal-based changes (requires user approval)
  - Snapshot history for rollback

All modules include:
- Tauri commands for frontend integration
- Unit tests
- Re-exported types via mod.rs

+//! Context Compactor - Manages infinite-length conversations without losing key info
+//!
+//! Flow:
+//! 1. Monitor token count against soft threshold
+//! 2. When threshold approached: flush memories from old messages
+//! 3. Summarize old messages into a compact system message
+//! 4. Replace old messages with summary — user sees no interruption
