/**
 * Minimal Zod → JSON Schema converter for our tool input schemas.
 *
 * Supports the subset we actually use: object, string, number, boolean, enum,
 * array, optional, default, nullable. Anything else degrades to `{}`.
 *
 * Avoids pulling in the full `zod-to-json-schema` package to keep the bundle small.
