at.happyproto.plugin.releaseExtension

The HappyView-specific half of a release, carried at extensions['at.happyproto.plugin.releaseExtension']. It is the plugin manifest, moved into the signed record so a consent screen renders without downloading the module. It is not trusted: the loader checks it against the module's plugin_info export and its import section, so a release that misstates what its WASM does is refused exactly as a checksum mismatch is.
