router: answer the task-list ask at stage 0 too, and mirror it in the fixture (V-467)

The capture half landed with the grammar in 87d1761. This is the exposure
the task asked to check for: IsTaskListQuery is a deterministic lookup that
only runs once the turn is already a query, so a phrasing the model calls
system never reaches it. The eval fixture was also missing both grammars,
which is only worth having while it is the daemon's grammar set.
