Addresses the #192 review: server usage documented in docs/grammar-draft.md
(incl. back-compat statement for the additive SUBMIT field and the #100-class
near-tie caveat); gateway pre-checks grammar payloads at 1 MiB (matching the
engine's gbytes bound); negative tests for non-dict response_format, empty and
oversized grammars, plus an explicit test that malformed GBNF passes the
gateway by design (engine fail-soft, draft-source semantics). Measured compile
overhead: 7.8 us/request typical schema, 17.9 us at the 32-level nesting cap.

Canonical write-up of the GRAMMAR= draft source: mechanism, why it pays in a
disk-streaming MoE specifically, usage/knobs, measured expectations by workload
shape (span-density dependence, from the #146 A/Bs incl. corrections), lossless
guarantees, bench discipline, prior art. Linked from the README feature bullet.
