Problem

When running curl -fsSL https://openclaw.ai/install.sh | bash on an upgrade, the installer runs openclaw doctor interactively. Doctor may reveal many skills with missing requirements (1password CLI, ffmpeg, jq, etc.). The user naturally wants to press Ctrl+C to abort, install those dependencies, and re-run later.

But Ctrl+C does not work:

1. @clack/prompts inside openclaw doctor catches SIGINT and treats it as "No" -- doctor exits 0, not 130
2. The install script has no trap ... INT -- only trap ... EXIT for temp file cleanup
3. The && doctor_ok=1 pattern prevents bash's cooperative SIGINT exit
4. should_open_dashboard is set to true before the interactive section, so the script continues to open a browser to http://127.0.0.1:18789/ which may be dead

The user pressed Ctrl+C to abort, but instead gets a browser tab to a dead address.

Expected behavior

Ctrl+C at any point during the installer should cleanly exit with temp file cleanup and a clear "Installation interrupted" message.
