chore: add semantic versioning and automatic changelog generation

- Add cliff.toml config for git-cliff with conventional commit parsing
- Create scripts/release.sh for automated version bumping
- Generate CHANGELOG.md from git history with semver tags (v1.0.0, v1.7.2)
- Release workflow: ./scripts/release.sh {major|minor|patch|VERSION}
