/**
 * Smoke test for ruvnet/ruflo#2132 — Windows-compatible init hook generation.
 *
 * Verifies that `ruflo init` generates a .claude/settings.json containing
 * node-based hook commands (no /bin/bash, no POSIX pipelines), and that the
 * platform detection correctly distinguishes Windows from POSIX.
 *
 * Runs on: ubuntu-latest, macos-latest, windows-latest (CI matrix)
 *
 * On windows-latest: asserts settings.json has node-based hooks
 * On ubuntu/macos: asserts settings.json has POSIX-compatible hooks and that
 *   no Windows-specific cmd.exe / %USERPROFILE% patterns appear
