vp dev: Ctrl+C in Ghostty/macOS prints escape sequence into prompt

[crusty-voidzero]

Summary

When stopping vp dev with Ctrl+C in Ghostty on macOS, an escape/control sequence is often printed into the shell prompt after exit.

Environment

• Terminal: Ghostty
• OS: macOS
• Command: vp dev

Repro

1. Run vp dev
2. Press Ctrl+C
3. Observe that an extra sequence is printed into the prompt after the process exits

Expected

vp dev should shut down cleanly without leaving terminal control / escape sequences in the prompt.

Notes

This looks like terminal cleanup / signal handling / TTY restoration not fully resetting on exit.

Experiencing this as well.

Workaround: type reset blindly after the crash.
