feat(map): implement Local Map Editor (Optimistic UI)

- Add geometric math engine (roborock/map/geometry.py) for coordinate conversion
  between image space (pixels), grid space, and robot space (mm)

- Add virtual state machine (roborock/map/editor.py) with:
  - EditObject base classes for virtual walls, no-go zones, room split/merge/rename
  - VirtualState with undo/redo functionality
  - Structural vs additive edit classification
  - Inverse command generation for rollback support

- Add translation layer (roborock/map/translation.py) with:
  - Protocol-specific translators (V1 and B01 Q7)
  - Two-Stage Sync pattern implementation
  - Map backup/restore for rollback

- Add verification loop (roborock/map/verifier.py) with:
  - Polling-based verification of applied edits
  - Per-edit-type verification logic
  - Map version checking for state drift detection

- Add CLI commands for map editing:
  - split-room: Split a room vertically or horizontally
  - merge-rooms: Merge multiple rooms
  - rename-room: Rename a room
  - add-virtual-wall: Add a virtual wall
  - add-no-go-zone: Add a no-go zone

- Add comprehensive tests for geometry and editor modules
- Update map module exports
