Subject: [PATCH] ci: add stale issue/PR bot

Add GitHub Actions workflow using actions/stale@v9 to automatically
mark and close inactive issues and PRs.

- Issues stale after 90 days, closed after 14 more days
- PRs stale after 60 days, closed after 14 more days
- Runs weekly (Monday 6am UTC) + manual dispatch
- Exempts: anything with a milestone, bug/security/process/enhancement labels

Closes #43
