Module memory 

In-memory implementations of runtime stores.

Provides MemoryRunStore, an ephemeral RunStore backed by tokio::sync::RwLock-guarded HashMaps. Useful for testing and single-process deployments where persistence is not required.

Architecture

Each run is stored as three in-memory maps:

• runs — RunRecord keyed by Uuid.
• events — RunEventRecord vectors keyed by run UUID.
• projections — Materialised RunState projections updated transactionally on every event append.
