Issue 842 summary
Pressing Escape in the session picker returns to main, prints “No session selected”, and leaves the process running without input handlers. The TUI is stopped, but the app does not exit.
Root cause
initTheme(..., true) starts the theme watcher before the session picker runs. When the picker returns null, main() logs “No session selected” and returns without cleanup or exit. The fs.watch started by the theme watcher keeps the event loop alive, so the process stays running with no input handling. That matches the reported soft lock.
Proposed fix
Handle the parsed.resume cancel path by explicitly cleaning up and exiting. For example in packages/coding-agent/src/main.ts, after if (!selectedPath) { ... }, call stopThemeWatcher() and process.exit(0) (or return after stopping the watcher if you prefer to let the event loop end naturally). This mirrors the print mode cleanup.
Affected files
packages/coding-agent/src/main.ts (add cleanup and exit on resume cancel)
