Configuration for gateway sessions.

Attributes:
timeout: Session timeout in seconds (0 = no timeout)
max\_messages: Maximum messages to keep in history (0 = unlimited)
persist: Whether to persist session state. Defaults to True so a
gateway started from the out-of-box path remembers conversations
across restarts/redeploys via the SQLite transcript store. Set
`persist: false` in the config to opt into ephemeral, in-memory
sessions.
persist\_path: Path for session persistence
store: Persistence backend when `persist` is set — `"sqlite"`
(default: transcripts in a WAL SQLite DB with concurrent readers
and indexed lookups) or `"file"` (legacy per-session JSON files)
resume\_window: How long (seconds) a session stays resumable after disconnect
max\_inbox: Maximum queued messages per session (0 = unlimited, default 256)
metadata: Additional session metadata
mirror\_runtime\_state: Enable runtime state mirroring for native transcript replay (Issue #1943)
