Release v0.2.0 (#39)

* fix: resolve broken action SHAs in release workflow

Replace non-resolvable commit SHA references with semver tags:
- actions/setup-go: SHA → v6
- actions/upload-artifact: SHA → v4

* feat: add workflow_dispatch to release workflow for testing

Allow manual triggering with tag input and dry-run mode to test
the release pipeline without publishing artifacts.
