style(Mountain): simplify entry point comments in Library.rs

Clean up documentation comments for the main entry point function:
- Simplify module-level comment from explanatory to concise "Entry Point"
- Update doc comment to explicitly state "both mobile and desktop builds"

These are minor documentation improvements for clarity without changing any functionality.
