/**
 * Catalog integrity launch gate.
 *
 * Asserts that EVERY TOOLS catalog entry is fully wired end to end:
 *   - Has a live API route (POST returns non-404)
 *   - Has a frontend tool-registry entry with a Settings component
 *   - Has a display mode in TOOL_DISPLAY_MODES
 *   - Has an API process-fn registration OR is in REGISTRY_EXEMPT
 *
 * The existing drift guards (tool-route-drift, tool-registry-drift) check
 * individual layers in isolation. This test is the cross-cutting launch gate:
 * one assertion that no tool is half-wired across all three layers combined.
 *
 * The TOOLS.length is checked dynamically -- never hardcoded -- so the gate
 * cannot silently drift when tools are added or removed.
