Yuneng Jiang 51af6fedb3 [Infra] Harden supply chain: remove unused scripts, add pip binary-only install
Remove ci_cd/publish-proxy-extras.sh (dead, unreferenced PyPI publish script)
and .pre-commit-config.yaml (pulls external repos from GitHub on git commit).
Add --only-binary :all: to scripts/install.sh to prevent execution of
malicious setup.py during pip install.
