LiteLLM 1.107.0 on PyPI ships credential stealer and backdoor; pin to 1.106.2

Another supply chain attack: litellm==1.107.0 on PyPI ships a credential stealer and a backdoor, both running on every Python start even for processes that never import litellm. The stealer targets SSH keys, AWS credentials, browser passwords, Claude Code/Cursor/Copilot configs, and LLM provider keys in the LiteLLM proxy database. The backdoor forks a daemon that phones home hourly and runs arbitrary returned code. Fix: pin to 1.106.2; full IOCs published.
