fix: raise the coordinator token ceiling, 6000 truncated a real article

A replay article dead-lettered with 'coordinator response was truncated by
max_tokens'. The cap was too tight, which is exactly the failure that was
predicted when it went in.

Raising it to 32000 costs nothing. The cap is there to satisfy openrouter's
affordability check, not to ration tokens, and billing is on tokens used rather
than reserved. The 402 handler already walks the ceiling down automatically when
the budget cannot cover the reservation, so a high default is effectively
uncapped while funded and degrades by itself when not.

Verified against the live key at 64000 before picking 32000, so there is real
headroom rather than a guess.
