Set reasoning-budget 16384; measurement shows it buys nothing here

Deployed as requested, then verified. On the same problem 4096 and 16384
give the same correct answer, but 16384 uses 17417 tokens instead of 5325
(~6 min vs ~2 min) and spends the extra budget in a repetition loop
("Maybe it's a^2+b^2=c^2+7?" repeated) rather than converging.

The premise for raising it -- thinking was truncated, so it needs room --
did not survive measurement. Documented; the value is left at 16384 as
requested rather than reverted unilaterally.
