feat(kanban): Interactive Kanban board with real-time task tracking (#83)

* feat(kanban): add Kanban board with task-manager skill, modal UI, and desk clutter

Implement a full Kanban board system for tracking agent tasks:
- Add task-manager skill with shared JSON task store for persistence
- Render board as a floating modal over the live 3D office (not immersive)
- Auto-create tasks from actionable user messages with heuristic filtering
- Sync task status through OpenClaw agent lifecycle events
- Collapse task details panel by default, expand on card click
- Add dynamic desk clutter (papers, folders, etc.) reflecting active task count
- Exclude done tasks from desk clutter count
- Extract KANBAN_CLUTTER_OFFSET for easy positioning adjustment
- Add install flow with progress bar for the task-manager skill
- Include unit and e2e test coverage

* feat(kanban): production-harden task board with AI-free classification, resilient persistence, and modal UX

- Harden shared task store with atomic writes, payload size limits, and server-side enum validation
- Add client resilience: request timeouts (AbortController), exponential backoff retries, poll deduplication
- Implement optimistic UI with rollback on all card mutations (update, move, archive)
- Add modal accessibility: focus trap, Escape to close, aria-modal, keyboard card navigation
- Trust OpenClaw agent lifecycle phase=start as task classification signal instead of regex heuristics
- Keep regex heuristic only as lightweight filter for direct chat events (conversational noise)
- Expand verb recognition with typo tolerance and broader action vocabulary
- Create tasks from agent runs even when no chat event is received (external channel support)
- Merge dual header bars into single bar; reposition close button outside modal corner
- Exclude done tasks from desk clutter count; make clutter position configurable via KANBAN_CLUTTER_OFFSET
- Update default furniture layout to match user configuration
- Ensure kanban_board furniture persists in local storage across sessions
- Add comprehensive test coverage for store, API route, and controller logic
