규칙 13.4

Every change must pass the mechanical gates: bun run build; bun run test, with surface-names.test.ts, intrinsic-coverage.test.ts, capability-reachability.test.ts, determinism.test.ts, api-surface.test.ts, emit-reflection-conformance.test.ts, and the emit goldens among them; bun run gate:compile; the docs snippet test src/compiler/ts/doc-snippets.test.ts, which compiles every snippet of the surface document.
