feat: v2.5.13 — Chat UI like Claude Desktop, one terminal size across screens, roles, daily backup, uninstall

- Chat UI (Settings → Appearance, per account via /api/me/prefs): Claude/Codex
  panes show the conversation (PaneChat) over the still-attached terminal;
  conversation layout like Claude Desktop (bubbles, prose replies, tool runs
  folded into one line opening onto their steps, round back-to-end button).
- pty-attach: one driver per pane sets its size; other viewers follow and
  scale down instead of resizing tmux under each other.
- Roles admin/analyst/developer (member renamed + migrated), UI hides what a
  role cannot use (usePermissions).
- Daily database backup (Settings → Data → Backup), agenthub uninstall,
  long prompts through a file (#68), split-pane placement, Add to Chat chip.
