// manifest.proto — the static plugin manifest (WO-WZ-001).
//
// PluginManifest is the wire form of everything that is *static data* in
// core/plugin/registration.go (PluginRegistration). It is produced once at
// publish time by calling the guest's DESCRIBE hook and stored as manifest.pb
// inside the .bnp artifact; the CMS loader reads it without instantiating the
// wasm module.
//
// Function-valued registration fields cannot cross the wire; they map to
// either a hook (Load/Unload/JobHandlers/MediaHooks/HTTPHandler), a boolean
// presence flag here, or an artifact directory (Assets → assets/,
// Schemas → schemas/, Migrations → migrations/). See core/docs/wasm-abi.md
// for the full field-by-field mapping.
