Fixes #192

This PR implements from_handle() static methods for Kernel classes enabling interoperability with foreign CUDA handles.

✨ Key Changes

  1. Kernel.from_handle()
  2. Thread Safety Improvements
    2.1. Added thread-safe lazy initialization using double-checked locking pattern
    2.2. Refactored global state access through helper functions that ensure initialization
