Feature/optimized ci workflow (#16)

* Optimize CI workflow: separate tests and release

- Move release job to separate release.yml triggered only on master push
- Add PR verification to release workflow (prevents releases from admin bypasses)
- Rename job display names to generic: Lint, Security, Coverage
- Skip expensive jobs (tests, coverage, outdated) on merge queue branches
- Keep Lint and Security running for merge queue status checks
