Module storage 

Session persistence backends. Session storage for persisting and resuming agent conversations.

The backend is pluggable via the Storage trait. Two built-in implementations:

• JsonlStorage — one JSON line per message, on disk, under <dir>/<session_id>.jsonl.
• NoopStorage — black-hole; useful for tests and ephemeral sessions.

Structs

JsonlStorage

On-disk JSONL backend. Each message is serialised to one line; the file is named <session_id>.jsonl inside the configured directory.

NoopStorage

Storage backend that discards everything — useful for tests / ephemeral sessions.

SessionMetadata

Session metadata persisted alongside messages so a resumed session can restore turn IDs, metrics, and file-read state.
