Subject: [PATCH] feat: migrate CI and releases from GitHub Actions to Gitea
 Actions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Retarget GoReleaser to publish to Gitea (gitea_urls, release.gitea,
changelog.use: gitea). Add Gitea Actions workflows for build/test,
release, and benchmarks — adapted from GitHub equivalents with macOS
jobs and SLSA provenance dropped. Old .github/workflows/ kept in place.
