ci: overhaul pipeline — caching, GoReleaser, govulncheck

- Add module + build cache to CI (was only caching go-build, not go/pkg/mod)
- Declare explicit Alpine container instead of relying on runner image
- Drop redundant go vet (already in golangci-lint)
- Add govulncheck job for dependency CVE scanning
- Add GoReleaser config for Gitea-native binary releases + checksums
- Replace .github/workflows/docker.yml with .gitea/workflows/release.yml
- Docker multiarch (amd64+arm64) via buildx in release workflow
- Dockerfile: add --mount=type=cache for mod/build, add -trimpath
