fix: bound max_tokens on the remaining llm callers

signal, augor and consolidation had the same unbounded request as the
coordinator, so switching to a model with a 131k output window made all three
402 on every call while the coordinator itself was fine. Found them by grepping
for the endpoint rather than waiting for each one to surface in the logs.

Sized per worker rather than one global number, since these produce more than
the coordinator's small json object.
