feat(agent): the transcript on by default

First landed flag-gated: the mechanics were unproven at coding-traffic
scale and the view changes what the model sees past the budget. The
claw then ran every surface on it and nothing fell over, the only user
is the deployment's own, and the sessions most likely to hit the
budget were the ones least likely to find a flag. Below the budget the
decorator is a pass-through, so the default's only always-on cost is
the zoom spec in the prompt.

transcript: None is the off switch; rhema-code spells it
--no-transcript, the claw's transcript: false now writes the resolved
value so false still means off. Saved sessions view fine: the log
stays complete and the view derives per request. The system preview
names zoom too, so what is previewed is what turns send.
