/**
 * The enumerable names at one node of the callable tool tree - namespace names at the root,
 * tool/namespace names below - powering `Object.keys(tools)` and `for...in` over tool
 * references. A callable tool is a leaf and enumerates as `[]` (like `Object.keys` of a
 * function in JS). An unknown path is an `UnknownTool` error pointing at the working
 * discovery idioms, mirroring how calling an unknown tool fails.
