v1.10.4: booterm mobile UX — copy/paste, swipe-close, send-to-chat, search

- Long-press selection + floating menu (mobile + desktop right-click): Copy,
  Paste, Select All, Search, Send to chat. Tap-outside / Esc dismiss.
- Pane-header Paste button (📋) for iOS user-gesture clipboard read.
- Swipe-left-to-close on mobile pane pill with red "Close" overlay and
  translateX visual hint; spring-back below 80px threshold.
- Send-to-chat reverse path: chatInputsRegistry + sendToChat event mirror
  the existing terminalsRegistry pattern. ChatInput appends with newline
  separator on receive and focuses (no auto-send).
- Scrollback search via xterm-addon-search@^0.13.0: SearchBar overlay with
  N-of-M match counter (onDidChangeResults), Enter/Shift-Enter cycling.
- Cmd/Ctrl+F intercept in Session.tsx when active pane is terminal; xterm
  also intercepts when focused. Browser native find passes through elsewhere.
- terminalsRegistry signature extended with openSearch + paste callbacks.

Includes deferred CLAUDE.md updates documenting v1.10/v1.10.1/v1.10.2/v1.10.3
learnings (uid 1000 collision, libc match, two event buses, vite proxy order,
mobile pane URL sync, xterm canvas selection).
