Previously, users had to explicitly read the CUA_API_KEY environment variable
and pass it to the Computer/CloudProvider constructor. This change makes the
API key parameter optional and automatically reads from the CUA_API_KEY
environment variable if not provided.
Changes:
- CloudProvider.__init__: Made api_key parameter optional, reads from CUA_API_KEY env var
- Computer.__init__: Added fallback to CUA_API_KEY env var for api_key parameter
- Updated documentation examples to show simplified usage without explicit api_key
- Updated cloud_api_examples.py to demonstrate the new simpler pattern
This provides a cleaner API while maintaining backward compatibility with
explicit api_key parameter passing.
