Terminals spawned by `claudemesh launch` were dropping keystrokes at
claude's prompt and showing the launch wizard re-rendering on top of
claude's TUI. Two compounding causes:
1. spawn() + child.on('exit') kept the parent node event loop alive
during claude's lifetime. Any stray readline 'data' listener or
late render from the wizard could fire on the inherited stdin/
stdout, stealing keystrokes or painting over claude's Ink TUI.
2. Raw mode / alt-screen / hidden cursor set by the wizard helpers
was not reliably restored before the handoff.
Fix:
- Swap spawn for spawnSync so the parent event loop is fully blocked
while claude runs. No listener or setImmediate can fire during
claude's lifetime.
- Hard TTY reset right before the spawn: setRawMode(false),
removeAllListeners on stdin, show cursor (ESC[?25h), exit alt
screen (ESC[?1049l). Defensive — survives partial wizard cleanup.
- Move cleanup() registration to process.on('exit') so it runs
synchronously on every exit path (normal, signal, throw).
- Preserve signal forwarding: if claude dies from a signal, re-raise
the same signal on the parent so exit codes propagate correctly.
Bumps to v0.10.6.
