Ship reasoning-budget 8192 as the compromise

Third data point: 8192 also gives the correct answer, at 9041 tokens
between 4096's 5325 and 16384's 17417. All three runs hit the ceiling
exactly -- the model never terminates thinking on its own, it fills
whatever budget it gets. Only the content changes: derivation at 4096,
second-guessing at 8192, a flat repetition loop at 16384.

On this problem the budget is a pure latency dial with no measured quality
effect. 8192 leaves room to finish a derivation without paying for the spin.
