fix(ci): improve logging and error handling in automated-pr-review.mjs

- Wrap `main` execution in try-catch block to ensure process exits with code 1 on failure.
- Update `runCommand` to throw meaningful errors on spawn failure (e.g. command not found).
- Add explicit check for `gh` CLI availability in CI environment.
- Improve git command error logging in `getChangedFiles` to capture stderr (e.g. "no merge base").
