 * Sets `Content-Security-Policy` on the Vite dev server from the local

 *
 * The policy is built once when the server starts and rebuilt only when
 * `manifest.json` changes (via Vite's file watcher), so the request path
 * stays I/O-free. In dev we also inject a small browser helper that listens
 * for CSP violations and prints a console.warn with a copy-pasteable
 * updated `manifest.json` for whatever was blocked.
