Repo-level secrets creation is broken on this Forgejo instance
(InsertEncryptedSecret fails with UTF-8 byte-sequence error, likely
a text-vs-bytea column type on the secret table). The fix is in
upstream Forgejo v16; until then, ${{ secrets.GITHUB_TOKEN }} (auto-
provided by the runner, scoped to contents: write for the current
repo) keeps the release workflow operational without any UI setup.
When the instance is upgraded and the secret table is migrated,
revert this commit to switch back to ${{ secrets.RELEASE_TOKEN }}
for least-privilege.
Adds .forgejo/workflows/release.yml: triggered by tag push or
workflow_dispatch, it validates the tag/CHANGELOG parity (stable /
preview / unstable), builds the PostIt Android APK via the existing
Dockerfile (--target build-env), and publishes a Forgejo release with
the APK as an asset via rasterstate/forgejo-release-action@v1.
Mirrors the validate-release logic of .github/workflows/docker-publish-android.yml
so the two channels (Forgejo source-of-truth + GitHub mirror) stay
consistent. Authentication uses ${{ secrets.RELEASE_TOKEN }}, a Forgejo
PAT scoped to write:repository configured in the repository's Actions
secrets.
