TashaSkyUp 7cf82171e5 Make environment management non-polluting and safe
This commit implements a clean architecture where environment variables
are only read, never set, ensuring compatibility with other ComfyUI
packages.

The changes: - Remove all code that sets global environment variables -
Clean up config.yaml to remove API key placeholders - Add documentation
for safe environment handling - Add comprehensive tests to verify
non-polluting behavior - Ensure backward compatibility for other
packages

The commit includes detailed docs explaining the clean architecture and
safety guarantees for package compatibility.
