feat: Claude Agent integration + cookbook reconnect + UI polish

- Claude Agent integration: AGENT_CONFIGS.claude, INTG_TYPES.claude,
  setup_claude_routes + integrations/claude/ skill bundle. Wired in
  app.py alongside the existing Codex integration; same scope-gated
  /api/codex/* backend; agent form has new description so users know
  it's setup for an external CLI, not an agent streamed inside Odysseus.
- Remove mark_email_boundaries action: not good enough yet. Stripped
  from task UI, scheduler defaults, registry, tool schema, clear-cache
  route. Added to RETIRED_HOUSEKEEPING_ACTIONS so existing rows + their
  task_runs auto-purge on startup.
- Cookbook download reliability: "Reconnect" fix button in the crash
  diagnosis runs _reconnectTask after probing has-session. 30s confirm
  window before marking a download "done" — kills the Finished/Downloading
  flicker when tmux briefly drops between captures.
- Mobile UX: tap anywhere on a note card body opens the editor;
  Update button morphs to Archive when no text was edited; bell icon
  accent-colored; chip-trashing notif pills fade so only the icon
  rotates into the trash zone.
- Settings integrations: SVG-per-provider in email + API preset
  dropdowns, custom drop-up-aware menus, accent sub-header icons
  (IMAP/SMTP), consistent card styling between list + edit, contacts
  Edit/Delete icons, agent form description copy.
