Add GoReleaser configuration and update Makefile for streamlined builds

- Introduced .goreleaser.yaml for automated release management.
- Updated Makefile to utilize GoReleaser for building the jiggablend binary.
- Added new workflows for release tagging and pull request checks in Gitea.
- Updated dependencies in go.mod and go.sum, including new packages for versioning.
- Enhanced .gitignore to exclude build artifacts in the dist directory.
