nntrivi2001 c7e934b4b4 fix(run): stop the terminal wheel from typing arrow keys, re-attach dropped sockets ...

Three separate reasons the Workspace terminal looked unscrollable:

- xterm falls back, on an alt-screen buffer whose program has not enabled
  mouse tracking, to translating each wheel notch into a cursor-key press.
  Inside a `claude` pane that reads as arrow up/down, so scrolling walked the
  prompt history. A custom wheel handler returning false suppresses only that
  emulation branch; real mouse reports come from a separate listener xterm
  registers when the program does request wheel events.
- TerminalView never reconnected, so a server restart left the pane frozen on
  its last painted frame — still live-looking, but swallowing every keystroke
  and mouse report. It now re-attaches 1.5s after an unexpected close and
  stops only on the server's `exit` frame; tmux keeps the session, so the
  re-attach repaints in full.
- tmux repaints the whole pane, so xterm's own scrollback is always empty and
  its viewport scrollbar renders as a groove with no thumb that cannot move.
  Hidden, since scrolling there goes through mouse reports, not the DOM.
