- Full task edit modal: title, description, status, priority, tags, findings
- Worklog sync endpoints POST /api/v1/worklog/sync + sync-activity
- Worklog empty state with curl command + paste-to-upload modal
- Font Awesome 6 throughout, no emojis
- Indigo topbar (bg-indigo-950)
- Fix Knowledge rendering: r.documents, r.files, r.available_agents/skills
