ci: add automated version bump and tagging from conventional commits

Add version.yml workflow that runs on pushes to main, parses conventional commit messages since the last tag, determines the semver bump (feat=minor, fix=patch, breaking=major), updates Cargo.toml version, commits, and pushes a version tag. The tag push triggers the existing release.yml publish workflow. Skips chore(release) commits to prevent infinite loops.
