/**
 * Manual end-to-end check for the Windows crossSpawn fix.
 *
 * Reproduces the auto-updater failure: `bun` on PATH only as npm `.cmd`
 * shims (no real bun.exe in any PATH directory). Temporarily hides any
 * bun.exe in the npm shim directory, then runs crossSpawn(['bun', ...]).
 *
 * Run with: bun scripts/e2e-windows-spawn.ts
 * Expected on Windows: exit 0 and a printed bun version.
 * Before the fix: spawn error ENOENT for 'bun'.
