InstantDB: frozen sibling tab parks the IndexedDB kv lock and blocks client boot indefinitely

@instantdb/core boot (subscribeAuth, getAuth, first query) waits unboundedly on reading the kv object store of instant_<appId>_<v>. If any other browsing context on the same origin holds a readwrite transaction on that store, boot blocks with no timeout and no fallback. A tab that the OS process-freezes mid-transaction (Android's cached-app freezer; SIGSTOP on desktop) holds that lock indefinitely — the browser never aborts it, because the transaction still has a request in flight.

// Reproduces InstantDB's response shape for optional fields under different
// permission/value combinations. Run with:
//
//   npm i @instantdb/admin
//   INSTANTDB_APP_ID=... INSTANTDB_ADMIN_TOKEN=... npx tsx instantdb-optional-field-shape.ts
//
// The app must have the schema + perms below pushed first:
//
//   npx instant-cli@latest push schema -p admin -a $INSTANTDB_APP_ID -y
//   npx instant-cli@latest push perms  -p admin -a $INSTANTDB_APP_ID -y
