Fix critical issues from spec review:
- Correct model.go line count (712, not 19K) and adjust Phase 1-1 scope
- Acknowledge existing chat/freeze implementations, rescope accordingly
- Add data model definitions (structs, BoltDB schemas) for all new entities
- Move logging and config externalization to Phase 1 (foundation)
- Align floor themes with boss patterns
- Add testing strategy, data migration plan, and admin API contract
