+/**
+ * Tool dispatch table.
+ *
+ * Maps every MCP tool name to a handler that takes the runner + raw args and
+ * returns the tool response. Extracted from index.ts so tests can exercise
+ * dispatch as a pure data structure (no Server / stdio / lifecycle setup).
+ *
+ * Behavioral contract preserved from the original switch in index.ts:
+ *  - Each name routes to the same handler it did before.
+ *  - Unknown tool names throw McpError(MethodNotFound, ...) — see
+ *    `dispatchToolCall`.
