ci(github): add GitHub Actions CI and release workflows for k3nnyfr/releaser mirror

- .github/workflows/ci.yml: same vet/staticcheck/test/build checks as Gitea CI
- .github/workflows/release.yml: same five binaries and build flags as the
  Gitea release workflow, published with gh release create
- docs: mention the GitHub mirror and both release pages; GitHub Actions
  example downloads from GitHub releases using RUNNER_OS/RUNNER_ARCH
- docs: fix broken latest/download URL, clone URL and Go version requirement

+## [Unreleased]
+
+### Added
+
+- **GitHub mirror** — the repository is mirrored from git.k3nny.fr (still the primary source) to [github.com/k3nnyfr/releaser](https://github.com/k3nnyfr/releaser)
+- **GitHub Actions workflows** — `.github/workflows/ci.yml` runs the same vet / staticcheck / test / build checks as the Gitea CI; `.github/workflows/release.yml` builds the same five binaries (same names, same `-trimpath -ldflags="-s -w -X main.version=<tag>"` flags) on `v*` tags and publishes them with `gh release create`, so every new release is available on both forges
+
+### Changed
+
+- **Installation docs** — README gains an Installation section; `docs/content/installation.md` lists both release pages and shows the GitHub download URL
+- **GitHub Actions example** — `docs/content/ci-integration.md` now downloads the binary from GitHub releases with an explicit version, picking the platform from `RUNNER_OS` / `RUNNER_ARCH`
+
+### Fixed
+
+- **Broken download URL in the GitHub Actions example** — `releases/latest/download/releaser-linux-amd64` never matched a real asset (asset names embed the tag)
+- **Build-from-source instructions** — clone URL was `…/k3nny/releaser/releaser.git` (404); stated Go requirement was 1.21+ while `go.mod` requires 1.26
+
 ## [1.10.0] - 2026-07-16

 Standard tools like `semantic-release` are designed for trunk-based development. In a GitFlow setup with versioned release branches (`release/1.1`, `release/1.2`), they either fail to respect the branch's version range or require brittle configuration.
