## Summary
- Add Renovate configuration to automatically track Easy-RSA releases
- Add GitHub Action to auto-update SHA256 hash on Renovate PRs
## How it works
1. **Renovate** detects a new Easy-RSA release → creates PR updating
`EASYRSA_VERSION`
2. **GitHub Action** triggers on the PR → downloads tarball → computes
SHA256 → commits fix
3. PR is ready to merge with both version and hash updated

I intentionally updated to the second-to-last version in

to test if this works.
