Greptile Summary

This PR converts the unitree_webrtc compatibility module from eager loading to lazy loading. The legacy module aliases are now imported on-demand using __getattr__ instead of being loaded immediately at package import time. The implementation correctly maintains the original behavior by caching imported modules in sys.modules, ensuring that modules are only imported once and that the aliased paths remain available for any code expecting them. This change reduces startup time by deferring imports until they're actually needed.

Confidence Score: 5/5

• This PR is safe to merge with no risk
• The change is a straightforward refactoring that converts eager module loading to lazy loading using the standard Python __getattr__ pattern. The implementation correctly maintains the original caching behavior, follows existing patterns in the codebase, and only affects a compatibility/legacy module with no breaking changes to the public API.
• No files require special attention

as far as i can tell this init.py is not neccessary for anything
