/**
 * Cross-platform shim helpers for spawning external binaries.
 *
 * Why this exists:
 * - On Windows, Node's `child_process.spawn` does NOT auto-resolve PATHEXT
 *   like the shell does, so `spawnSync('rg', [...])` fails with ENOENT even
 *   when `rg.exe` is on PATH. We have to ask for the `.exe` (or `.cmd`)
 *   variant explicitly.
 * - npm-installed CLIs (`npm`, `npx`, `localnest`) ship as `.cmd` shims on
 *   Windows. Same problem, same solution.
 *
 * Centralizing this here keeps the platform check in one place instead of
 * sprinkling `process.platform === 'win32'` ternaries across every spawn site.
