fix(cron): trust agent output when channel is unresolved without explicit delivery (#92817)

resolveCronChannelOutputPolicy checked deliveryRequested === false
when there is no channel. Since deliveryRequested is optional
(?: boolean), undefined and missing opts both returned false,
blocking the hasRecoveredToolWarning rescue path for --no-deliver
cron runs whose agent recovered successfully.

Change === false to !== true: when no channel exists, prefer the
agent's final visible text unless delivery was explicitly
requested.

Fixes #90664
