How can external developers contribute to GLM and ZCode products?

[Ruzibekov]

Hi ZCode team,

I'm a developer who uses ZCode daily (desktop app and CLI). I'd like to contribute to GLM and the products built on it — for example, ZCode mobile apps, the desktop app, plugins, skills, and the models themselves.

Could you clarify:

1. Is there an open-source contribution path (public repos, good-first-issues, CLA) for GLM or ZCode tooling?
2. Is there a public API/SDK for building on GLM (plugins, MCP servers, integrations) that community developers can use?
3. Do you accept community plugins/skills for ZCode (mobile/desktop)? Is there a marketplace or review process?
4. Are there beta programs, bug bounties, or structured feedback channels where outside developers can help improve GLM-based products?
5. Do you have an advocate/community program? I could help with Uzbek/Central Asia localization, docs, and tutorials.

I'm ready to contribute code, testing, localization, and real-world feedback. Please point me to the right channels.

(Cross-linking context: I also posted this as a question here rather than a feature request — happy to move it to Ideas or Discord if that's a better fit.)
