/**
 * Schema compatibility audits.
 *
 * Each provider has a different idea of what JSON Schema features it accepts
 * for tool definitions. The normalizers in `normalize.ts`, `strict-mode`,
 * and `adapt.ts` rewrite incoming schemas to fit. This module is the
 * *audit* counterpart: it walks a (presumably already-sanitized) schema and
 * reports any feature the target provider would reject. Tests use it to lock
 * down the contract; the runtime uses it to fail-open with diagnostic logs
 * rather than silently shipping a broken tool definition.
