feat: add Notes type, collaboration, and shared task review

- Add type column (task/note) to tasks table with 5 migrations
- Notes are never auto-archived or purged (persistent references)
- Add assignee/shared_by columns for cross-account collaboration
- New MCP tools: assign_task, review_shared_tasks
- bridge_push: cross-account push to assignee's memory-bridge repo
- bridge_pull: stage shared_tasks in pending_shared_tasks (security)
- UI: Notes tab, type dropdown, Convert context menu, [N] prefix
- Kanban: NOTE badge on cards
- Digest: filter to tasks only, --include-notes CLI flag
- Hook: assign_task added to bridge_auto_sync WRITE_TOOLS

BREAKING: shared_tasks from other accounts now require explicit
approval via review_shared_tasks(action="approve") before import.
