v0.2.0

• certclock check: CI and cron gate with exit codes 0/1/2/3, ad hoc --host/--path collection or --db, --fail-on warn|crit|never, and text, json, or markdown output
• GitHub Action (action.yml) that runs check and writes the Markdown report to the job summary
• report.md: Markdown summary written next to the other reports
• ROADMAP.md with good first issues, issue forms, and a pull request template
• Renamed the project from certpilot to certclock: package, CLI, environment variables, files and docs. Earlier changelog entries use the old name.
