/**
 * Quits the app.
 *
 * Uses the request-correlated native bridge and requires the calling window
 * to have the `app:quit` capability. Rust turns the authorized request into
 * a graceful host shutdown without round-tripping through Node/libuv.
 *
 * This is the only way to quit a murasaki app programmatically; there is no
 * other API for it. `useUpdate()`'s `install()` calls this after the backend
 * has staged a verified launcher handoff. The native host spawns the detached
 * apply-helper only after graceful shutdown succeeds, per the install → quit →
 * apply handshake (updater contract §7) — but it's a
 * general-purpose primitive, not an updater internal.
