fix: commit changelog before tagging to fix goreleaser dirty-state error (#36)

The release workflow generated CHANGELOG.md and RELEASE_NOTES.md but
never committed them before creating the git tag. Goreleaser's dirty-state
check caught the uncommitted files and aborted the release.

Now commits both files before tagging, and removes the redundant
changelog PR step since the changelog is committed directly to main.
