ci(release): replace goreleaser with custom build workflow

Replace GoReleaser with a custom GitHub Actions workflow that builds binaries for multiple platforms (linux/amd64, linux/arm64, darwin/amd64, darwin/arm64, windows/amd64) and creates multi-arch Docker images. This provides more control over the build process and removes the dry-run workflow input that was unused.

BREAKING CHANGE: Removed .goreleaser.yaml configuration file and goreleaser-based release tasks from Taskfile.yaml. Release process now handled entirely by GitHub Actions workflow.
