/**
 * ADR-124 §4.1 / §4.1a schema coverage tests.
 *
 * Guards:
 *  1. Every catalogued tool name appears in TOOL_NAMES and TOOL_INPUT_SCHEMAS.
 *  2. TOOL_INPUT_SCHEMAS has no extra (undocumented) keys.
 *  3. Each schema accepts its documented happy-path input without throwing.
 *  4. Each schema rejects structurally invalid input (Zod parse failure).
 *  5. Shared sub-schemas (NodeId, DurationS, SemanticPrimitiveKind) enforce
 *     their documented constraints.
