  -Create PermissionAuthorizer interface for PermissionClients
  +- Add `PermissionAuthorizer` interface matching `PermissionClient` to allow alternative implementations like the `ServerPermissionClient` in @backstage/plugin-permission-node.
  +
  +Breaking Changes:
  +
  +- Remove "api" suffixes from constructor parameters in PermissionClient
  +
  +```diff
  + const { config, discovery } = options;
  +- const permissionClient = new PermissionClient({ discoveryApi: discovery, configApi: config });
  ++ const permissionClient = new PermissionClient({ discovery, config });
  +```
