session-title/ — log-backed session-title capability family

Durable session-title state, one optional asynchronous provider seam, and two opt-in model-backed implementations. The built-in first-message fallback is part of the service, so every composition can title a session without an auxiliary model call.

Package	Role	ctx key
session-title/	Log fold, deterministic fallback, provider registry, and refresh API	ctx.sessionTitle
session-title-llm/	Shared route, prompt, timeout, stream, and validation helper	—
session-title-first-message-llm/	Optional provider using the first eligible human message	registers on ctx.sessionTitle
session-title-all-messages-llm/	Optional provider using every eligible human message	registers on ctx.sessionTitle

Only one provider may register at a time. The shared demo spine mounts the fallback service but leaves both model providers outside default composition, so deployments choose auxiliary cost and retitling cadence explicitly.
