the complete React setup, realtime API, and application guide.

What changed

Added the Fireclass logo and removed npm, license, and type shield badges.
Added Firebase Web app environment and client initialization guidance.
Documented the app-bound Fireclass entry, validated models, realtime Todo
workflow, and single-document subscriptions.
Added complete useQuery and useDoc state transitions, resubscription and
cleanup behavior, JSON query-value limitations, and ClientAdapter
capabilities.
Added Firebase Authentication, Security Rules, and App Check boundaries.
Expanded npm keywords for React hooks, realtime Firestore, Firebase client
SDK, typed models, validation, and Firestore ODM.
