Module cache 

WorkspaceCache — L2 cache interface for session workspace state.

This module defines the WorkspaceCache trait, supporting types, and the NoOpCache implementation that satisfies the trait with no-op behaviour. The trait is the seam used by multi-pod deployments to share workspace snapshots across replicas via an external store (e.g. Valkey/Redis).

Available implementations are NoOpCache (single-pod / local dev) and ValkeyCache (production multi-pod, behind the valkey feature). For single-pod deployments (and tests), NoOpCache is the default.
