/**
 * Contract: /dump tool catalog renders parameters as JSON Schema.
 *
 * Tools carry live Zod v4 schemas; the dump formatter must convert them to
 * the wire JSON Schema (same shape providers receive) instead of enumerating
 * the schema instance's internals (`def`, `shape`, stringified methods).
 * Legacy plain JSON-Schema parameters still pass through with TypeBox
 * bookkeeping fields stripped.
