Vouch Request: renyi9044-png (Python stderr deadlock fix)

[renyi9044-png]

Hi! I submitted PR #3392 to fix #3357 (Python subprocess deadlock with >64KB stderr).

What I fixed

• Removed hardcoded OTEL_LOG_LEVEL: "DEBUG" that was flooding stderr
• Filtered parent OTEL_* env vars from leaking to Python subprocesses

My background

• Python/TypeScript developer
• Experience with subprocess management and OpenTelemetry
• Found and fixed this issue by analyzing the root cause described in bug: python.runScript() deadlocks when Python subprocess produces >64KB stderr output #3357

Why I should be vouched

The fix is straightforward and addresses the contributing cause identified in the issue. Happy to make any adjustments needed.

Thank you for considering!
