OpenOSRS — open-source client, plugin API and GitHub plugin loading

Hey everyone, I'm Client0s. I'm maintaining an OpenOSRS fork for people who like building their own client features.

The client source is public, with a separate updating launcher, API docs and three small example plugins. Plugins load through GitHub repositories in the External Plugin Manager, so you can inspect their source and build your own.

A small starting point
The examples cover a welcome message, an NPC-count overlay and inventory changes. They use the same repository feature as other external plugins.

Built on the work of OpenOSRS and RuneLite contributors. Known compatibility limits are in the release notes; feedback and focused PRs are welcome.
