firestore_session_store library
A Firestore-backed SessionStore for Genkit agents.
Ported from the Genkit JS FirestoreSessionStore, this store persists
session snapshots as incremental JSON Patch diffs anchored to periodic,
sharded full-state checkpoints, so it scales to arbitrarily long sessions
without any single document approaching Firestore's 1 MiB limit.

SessionStorethat persists session snapshots as incremental JSON Patch diffs anchored to periodic, sharded full-state checkpoints.
Constants
- defaultCheckpointInterval → const int
- Default number of turns between full-state checkpoints.
- defaultShardSize → const int
- Default maximum size (in bytes) of a single shard / diff document. Kept well under Firestore's 1 MiB per-document limit so that no individual write can be rejected for being too large.
