Thank you for your pull request and welcome to our community. We could not parse the GitHub identity of the following contributors: Great Love.
This is most likely caused by a git client misconfiguration; please make sure to:

1. check if your git client is configured with an email to sign commits git config --list | grep email
2. If not, set it up using git config --global user.email email@example.com
3. Make sure that the git commit email is configured in your GitHub account settings, see https://github.com/settings/emails

Updated the submodule to the latest build (still 0.1.0, not yet released). Changes since the initial pointer:

• %property now parses attributes, type, and name like a native @property (previously an opaque token)
• Added outline.scm for symbol navigation (groups, hooks, subclasses, hookf, ctor/dtor, properties, Obj-C methods/interfaces, C functions)
• Added bracket/quote auto-closing, block comments, and overrides.scm scopes

Grammar corpus 7/7, all examples parse, all query files compile. CI is green.
