[BUG] Interactive menus (MCP, rewind) completely unresponsive on --resume

What's Wrong?

When resuming a session with claude --resume, interactive menus (MCP picker /mcp, rewind) render visually but accept no keyboard input whatsoever -- arrow keys, Escape, Enter, and Ctrl-C are all unresponsive. The only recovery is
force-killing the terminal window or kill -9 from another tab. Affects both iTerm2 and Terminal.app.

Fresh sessions (claude without --resume) work correctly every time.

What Should Happen?

Interactive menus should respond to keyboard input after --resume, identical to fresh sessions.

Error Messages/Logs

From claude --resume --debug-file /tmp/debug.txt, the following pattern appears immediately after startup and persists indefinitely:

  [STARTUP] showSetupScreens() completed in 4588ms   ← normal is <100ms
  [DEBUG] High write ratio: blit=0, write=31269 (100.0% writes), screen=477x244
  [DEBUG] High write ratio: blit=0, write=31506 (100.0% writes), screen=487x244
  [DEBUG] High write ratio: blit=0, write=31710 (100.0% writes), screen=488x244

  blit=0, write=100% never normalizes -- the renderer stays in full-redraw mode and never engages the overlay/menu input system.

  Also previously seen (with multiple sessions): Cannot acquire lock for 2.1.118 - held by PID XXXXX -- however the hang reproduces with only a single claude process running, so the lock conflict is not the sole cause.

  Potentially related open issue: #13287

Steps to Reproduce

1. Start claude and have a substantial conversation
2. Exit
3. Run claude --resume
4. Try to open any interactive menu (/mcp, rewind)
5. Menu renders but is completely frozen -- no key input accepted, including Ctrl-C

My computer crashed a few times, which may have been the trigger for this behavior.
