/**
 * Bun environment fix for Termux
 *
 * Bun on glibc/Termux has a bug where process.env and Bun.env return zero
 * entries even though the kernel provides the full environment. This preload
 * script reads /proc/self/environ and populates process.env.
 *
 * Usage: bun --preload /path/to/fix-env.js your-script.ts
