Greptile Summary

Updates the .internal-docs submodule pointer to the latest synchronized revision.

• Advances .internal-docs from fb472a6c to 38579a92.
• Makes no application, build, or runtime code changes.

Confidence Score: 5/5

The PR appears safe to merge because it only advances the internal-documentation submodule pointer and no concrete failure was identified.

The changed gitlink does not alter application or build code, and repository documentation states that the private submodule is not required to build BrowserOS.
