SNOW-3880829: detect_platforms() is not cached as expected

[etienne-lebrun]

Python version

Python 3.11.6 (main, Nov 7 2023, 15:13:01) [GCC 11.4.0]

Operating system and processor architecture

Linux-6.8.0-124-generic-x86_64-with-glibc2.35

What did you do?

detect_platforms() is decorated with @functools.cache (platform_detection.py), so platform detection should run once per process. But the only call site passes a fresh SessionManager clone on every call (auth/_auth.py, Auth.base_auth_data):

"PLATFORM": detect_platforms(
    platform_detection_timeout_seconds=platform_detection_timeout_seconds,
    session_manager=session_manager.clone(max_retries=0),
),

What did you expect to see?

Detection runs once per process; subsequent connect() calls reuse the cached result.
