Pull Request Overview

This PR improves and clarifies the documentation for the client-presence APIs by updating inline comments and API report annotations.

• Added documentation for internal types in packages/framework/presence/src/exposedInternalTypes.ts.
• Revised the API report markdown files to remove the "(undocumented)" markers and standardize the @System annotations.
