- Rewrite DiscordChannelSidebar with @dnd-kit drag-and-drop:
rooms are sortable within categories; dragging onto a different
category header assigns the room to that category
- Add inline 'Add Category' button: Enter/Esc to confirm/cancel
- Wire category create/move handlers in room.tsx via RoomContext
- Fix onAiStreamChunk to accumulate content properly and avoid
redundant re-renders during AI streaming (dedup guard)
- No backend changes needed: category CRUD and room category update
endpoints were already wired
Add the second half of the password reset flow: /password/confirm API
endpoint with token validation, transactional password update, and a
frontend confirm-password-reset-page with proper error handling for
expired/used tokens. Updates generated SDK/client bindings.
- Add workspace_my_pending_invitations() for listing pending invites
- Add workspace_accept_invitation_by_slug() to accept by slug without token
- Register new routes: GET /workspaces/me/invitations, POST /workspaces/invitations/accept-by-slug
