/**
 * @beacio/core/auto — Transparent Web Bluetooth polyfill.
 *
 * Usage: import '@beacio/core/auto';
 *
 * - Chrome/Edge (native bluetooth): no-op
 * - Safari iOS (with extension): ensures navigator.bluetooth maps to extension API
 * - Safari iOS (without extension): lazy-loads install prompt on first requestDevice()
 * - Unsupported platforms: no-op (graceful degradation)
 */
/**
 * Install the transparent W3C `navigator.bluetooth` polyfill for the current
 * platform (no-op on native/unsupported per the branches below). Runs once at
 * module load via the bottom-of-file call for `import '@beacio/core/auto'`
 * consumers; also EXPORTED so the consolidated `browser-auto` entry can invoke
 * it explicitly (a bare side-effect import is tree-shakeable under the package's
 * `sideEffects` allowlist). Idempotent: the module-level guard makes a second
 * call a no-op so the two entry points never double-register the permissions
 * shim or the extension-ready listener.
