Work handed to a second model, which may not ask

Browse Source 
subagent_run gives a self-contained piece of work to a helper carrying the
parent's connection, directory, model and effort, and hands its answer back as
the tool result. The mechanism is the one scheduled runs already use -- a hidden
chat, one turn, wake_chat, and a poll -- so tools, rounds, budgets, metrics and
steps all work with no second implementation. The two alternatives were
rejected where they had already been rejected once: a nested Generation is two
replies writing one transcript, and a one-shot complete() has no tools, which
schedule/runner.py records as useless for exactly this case.

Every restriction is a property of the child's row, applied by resolve_tools
after the gates, because a rule that lives in a system message is one a page the
model just read can argue with. No questions, no recursion, nothing that writes
unless the call asked for it and the parent's own mode would not have stopped
first, and commands only from a fixed read-only list -- in every mode including
Auto, because the task text can have come from a page.

Withdrawing ask_user turned out to be half of "nobody is watching". An approval
still built a card nobody could see and parked the reply until approval_timeout,
which from every screen is the feature not working. Chat.unattended is the
question now, and not the kind: _authorise answers with a refusal instead. A
scheduled task's chat had the same hole and is covered by the same flag.

Three bounds, counted where each is knowable: per reply on the parent's
Generation, instance-wide in a set a restart clears, and per helper in settings
of its own so one runs out of room long before the reply that asked. Past the
clock the helper is stopped rather than abandoned, so a partial answer comes
back with a sentence saying so.

Also: four gates had shipped into the scope menu with no name, taking the first
tool's label instead -- the canvas switch read "Canvas written". There is a test
that refuses a family without one.

"""Delegating a piece of a reply to a second, unattended model.
The whole risk of this feature is that the helper runs with nobody watching, so
almost every test here is about what it is *not* given. Restriction happens at
tool resolution, never in the prompt — so what these assert is the resolved set
and the row it comes from, not the wording that describes it.
The generation loop itself is stubbed. What it does with a chat is covered by
`test_generation.py`; what matters here is which chat it is handed.
