fix: Prevent deployment logs from appearing in PR comment

- Redirect all logging output to stderr in deploy_storybook function
- Only return clean URL or 'failed' to stdout for proper capture
- Add --commit-dirty=true flag to suppress git warnings
- Fix issue where entire deployment output was shown in comment link
