socket-patch-cli 3.2.0

//! Tests for alternate install configurations within ecosystems.
//!
//! npm packages can be installed by `npm`, `yarn`, `pnpm`, or `bun` —
//! each writes to `node_modules/` in slightly different ways. pypi
//! supports venv, pyenv, conda, system installs. This file exercises
//! the layout variants the crawlers must handle in production.
