feat(cron): title cron sessions from the job, not the [IMPORTANT] hint

A cron session's first message is the injected "[IMPORTANT: you are running as
a scheduled cron job …]" delivery hint, so with no explicit title the sidebar
and history rows fell back to that hint as their label.

Set the session title from the job (name → short prompt → id) with a run-time
suffix for uniqueness against the sessions.title index. Done after the run so
the agent's own INSERT keeps model/system_prompt — this only updates the title.
