fix: make the release workflow build and package a real Jellyfin plugin

The release workflow was copied from another project and could not succeed on any tag: it installed the .NET 8 SDK for a net9.0 project, published a JellyfinSso.csproj that does not exist, called a missing update_manifest.py, and zipped the entire publish tree instead of the three DLLs declared in build.yaml. Replace it with a tag-driven release: - Build with the .NET 9 SDK, injecting the tag version via -p:Version, -p:AssemblyVersion and -p:FileVersion so the assembly no longer carries a hardcoded 1.0.3.0. - Package via scripts/build_plugin.py, which emits the JPRM layout Jellyfin expects: the build.yaml artifacts plus a generated meta.json. The previous zips shipped without meta.json, which only worked for repository installs because Jellyfin synthesises one from the folder name. - Update manifest.json via scripts/update_manifest.py, keeping build.yaml as the single source of truth for plugin metadata. - Commit the zip and manifest to main and attach the zip to the Gitea release. Pushing uses the injected token, falling back to a RELEASE_TOKEN secret when the built-in one lacks write access. Also fix the published download URLs. manifest.json and the README pointed at pascallinxweiler/jellyfinplugin, which 404s; the repository is jellyfinsso, so the plugin repository could not be added to Jellyfin and no version could be downloaded. The workflow now derives the URL from GITHUB_REPOSITORY. Add a build workflow so main and pull requests are compiled and packaged. Co-Authored-By: Claude <noreply@anthropic.com>

 ## Build

+Requires the .NET 9 SDK and `pyyaml`. The script compiles the plugin and packages
+it the way Jellyfin expects — the DLLs listed in `build.yaml` plus a generated
+`meta.json` — into `dist/oidc-auth_<version>.zip`:
+
 ```bash
-dotnet publish Jellyfin.Plugin.OidcAuth --configuration Release --output artifacts
+pip install pyyaml
+python scripts/build_plugin.py
 ```

+Pass `--version 1.0.4.0` to override the version in `build.yaml`.
+
+## Release
+
+Releases are cut by pushing an annotated tag; the tag message becomes the changelog:
+
+```bash
+git tag -a v1.0.4.0 -m "What changed in this release."
+git push origin v1.0.4.0
+```
+
+`.gitea/workflows/release.yml` then builds the plugin at that tag, commits the zip
+to `dist/` on `main` together with an updated `manifest.json`, and attaches the zip
+to the Gitea release. Jellyfin picks the new version up from the repository URL below.
+
+Pushing needs a token with write access. Gitea's built-in `GITHUB_TOKEN` is used by
+default; if the repository does not grant it write access, add a PAT as the
+`RELEASE_TOKEN` secret.
+
 ## Install via plugin repository (recommended)
