docs: add CI/release documentation and ignore dist directory

Add `/dist/` to `.gitignore` to exclude locally built distribution
artifacts. Document the Gitea Actions workflow, release tagging, and
branch protection setup in the README.

 Run this from the repository root. The build and run helpers resolve that path automatically.
 
+## Gitea Actions and releases
+
+The `Tests` workflow runs the normal and GTK-tagged Go tests, `go vet`, and ShellCheck for every pull request and branch push. To make it mandatory for pull requests, open the repository's **Settings → Branches**, edit the protection rule for `master`, enable required status checks, and select **Tests / Go and GTK tests** after its first run. Workflow files can report the check, but the branch-protection rule is what prevents merging when it fails.
+
+Pushing a tag that exactly follows `vMAJOR.MINOR.BUG` runs the same test suite first, then builds and publishes a Gitea release:
+
+```bash
+git tag v1.3.519
+git push origin v1.3.519
+```
+
+The release contains a checksummed Linux x86_64 archive with `captioneer`, `captioneer-desktop`, the required Sherpa/ONNX shared libraries, the model download script, the README, and the license. The desktop command still requires GTK4 and GTK4 Layer Shell runtime libraries on the destination system.
+
+The release workflow uses Gitea's built-in `GITEA_TOKEN`; no personal token is required. In **Settings → Actions → General**, allow the workflow token `Read` access to code and `Write` access to releases. Gitea clamps workflow permissions to those repository settings, so a more restrictive maximum produces an actionable HTTP 403 during publishing.
