fix: address review findings in deploy-and-verify.php

- Fix #1: replace rm -rf with cross-platform PHP removeDirectory()
- Fix #2: sanitize URL in audit log (log hostname only)
- Fix #3: remove unused buildHealthArgs() and $healthArgs
- Fix #4: add random suffix to snapshot dir name for uniqueness
- Fix #5: fix constructor to match CliFramework pattern (no args)
- Fix #6: trigger rollback on deploy failure (partial deploy risk)
