Large World graph, agent platform, brain stack & dashboard rebuild

Frontend
- Large World: collapse org/company/team tiers into one expandable React Flow
  hierarchy (WorldFlow) with per-click expand, persisted node positions, a
  compact tree sidebar, wrench multi-select delete across levels, and a sized
  right slide-out (phone/tablet/full) showing an agent summary + drill button.
- Agent page: GitHub-style animated contribution grid (VitalsCard), collapsible
  System Prompt + Personality cards, restructured anatomy cards, bigger avatar
  with name/title header row, Markdown/JSON-aware rendering, brain registry +
  history, avatar generate/upload.
- User-icon menu (Infrastructure/Brains/Tools/Profile/Credits) + ToolPanel;
  Master Planner deploy wizard (Specialists/Swarm/Scheduled/Triggered);
  Team Runs view; reap-progress modal; dashboard is the single live interface.

Backend
- cm-brain crate (.brain as the agent definition) + brain apply/history.
- Hard-purge reap (FK-ordered) + sandbox release + SSE batch-delete.
- Swarm self-verifying loop, mode-aware planner, web.search tool, webhooks
  (migration 0013), org/company/team delete endpoints, scheduler sweeps.
