Update workflows and build process for enhanced metadata injection

- Upgraded GitHub Actions (`actions/checkout` to v4, `actions/setup-go` to v4, `goreleaser-action` to v4).
- Added detailed build metadata (`VERSION`, `COMMIT`, `BUILD_DATE`) to workflows.
- Unified metadata injection into binaries and Docker images.
- Enhanced `.goreleaser.yml` with checksum, snapshot, and changelog configurations.
