Can my team comment on prompts?

On any tracked prompt detail page, the Workspace section lets you:

1. Assign an owner from your team. Teammates come from your account or any Agency parent you are part of (the same scoping the rest of the app uses, e.g. site visibility).
2. Set a watch status - new, watching, fixing, done, ignored. Use it to triage a backlog of prompts that flagged citation gaps.
3. Drop comments. Plain text, 2000 chars, threaded by created_at. Author or admin can delete.

All three actions are CSRF-protected and gated by Pro / Agency. The data sits in tracked_prompts (assignee_user_id + watch_status) and prompt_comments (one row per comment).
