consciousness: teach the overflow gate anthropic's wording

The resuscitation path exists for exactly this: her thread passes the
model's ceiling, every pass is refused before a tool round runs, and she
can never reach `memory compact` herself. It did not fire. `prompt is too
long: 1285770 tokens > 1000000 maximum` matches none of the five patterns
the gate was written against on 08-13, when she ran on deepseek and the
only wording anyone had seen was "maximum context length".

So she reported the same failure every three minutes for half an hour
while holding the lever she could not reach.

Anthropic's body is now pasted into a test beside deepseek's, verbatim,
same rule as the comment above it: a matcher tested only on invented
strings has never been seen to fire. The second clause catches a token
count stated as over a maximum under a different preamble; both halves
are required so an "invalid max_tokens" complaint still reads benign.
