feat: add RMA (Relationship Memory Architecture) module v0.6.0

Complete RMA system for tracking relationship dynamics in roleplay:
- 10 new modules in src/rma/ (analyzer, memory-store, phase-manager,
  worldbook-sync, float-panel, confirmation-ui, timeline-view, etc.)
- Three-layer model: phases → memories (4 types) → emotional texture
- Post-processing AI analysis via CHARACTER_MESSAGE_RENDERED hook
- Dynamic world book entry toggling/rewriting
- Floating panel UI with 3 states (expanded/half/minimized)
- User confirmation flow (every_turn/important_only/auto modes)
- Settings panel integration with independent API config
- chat_metadata.cola_rma persistence
