chore(06-01): create facade types and directory structure

- Create apps/server/src/services/auto-mode/ directory
- Add types.ts with FacadeOptions interface
- Re-export types from extracted services (AutoModeConfig, RunningFeature, etc.)
- Add facade-specific types (AutoModeStatus, WorktreeCapacityInfo, etc.)

apps/server/src/services/auto-mode/types.ts
