feat(dist): add GHCR push and Homebrew tap to release pipeline

Docker releases now dual-push to Docker Hub and ghcr.io/lerkolabs/uptop.
GoReleaser brews section generates a Homebrew formula and pushes to
lerkolabs/homebrew-tap on GitHub.

Requires new Gitea secrets:
- GHCR_USERNAME / GHCR_TOKEN for GHCR login
- HOMEBREW_TAP_GITHUB_TOKEN for tap repo push
- GitHub repo lerkolabs/homebrew-tap must exist
