FirebaseFollowSource class final

FollowDataSource backed by Cloud Firestore.

Follow documents are stored in two sub-collections per user:

• users/{userId}/followers/{followerId} — who follows the user.
• users/{userId}/following/{targetId} — who the user follows.

A root follows collection is also maintained for easy querying.
