Phase 1 of user permissions feature:
- Add board permissions schema to D1 database
- boards table with owner, default_permission, is_public
- board_permissions table for per-user permissions
- Add permission types (PermissionLevel) to worker and client
- Implement permission API handlers in worker/boardPermissions.ts
- GET /boards/:boardId/permission - check user's permission
- GET /boards/:boardId/permissions - list all (admin only)
- POST /boards/:boardId/permissions - grant permission (admin)
- DELETE /boards/:boardId/permissions/:userId - revoke (admin)
- PATCH /boards/:boardId - update board settings (admin)
- Update AuthContext with permission fetching and caching
- fetchBoardPermission() - fetch and cache permission for a board
- canEdit() - check if user can edit current board
- isAdmin() - check if user is admin for current board
- Create AnonymousViewerBanner component with CryptID signup prompt
- Add CSS styles for anonymous viewer banner
- Fix automerge sync manager to flush saves on peer disconnect
Permission levels:
- view: Read-only, cannot create/edit/delete shapes
- edit: Can modify board contents
- admin: Full access + permission management
Next steps:
- Integrate with Board component for read-only mode
- Wire up permission checking in Automerge sync
- Add permission management UI for admins
