Pull request overview
Adds AI-generated titles for Agent Host sessions by seeding an immediate first-message fallback title, then asynchronously generating a short “utility” title via Copilot CAPI and persisting it as customTitle, with cancellation/guardrails to avoid clobbering manual renames or disposed sessions.
Changes:
- Introduces
AgentHostSessionTitleControllerto manage fallback title seeding, AI title generation, persistence, and cancellation. - Wires title generation into
AgentSideEffectson first user turn and cancels in-flight generation on session disposal viaAgentService. - Adds targeted unit tests covering generation success, failure, manual rename protection, cancellation, and fork/title skip behavior.

Adds AI-generated session titles for Agent Host sessions using Copilot utility chat completion after seeding the existing first-message fallback title.
The title workflow now guards against clobbering manual renames, skips pre-titled/forked sessions, cancels pending generation when sessions are disposed, and persists generated titles as custom titles.
