/**
 * Trazum as an MCP server.
 *
 * The point is narrow: an agent about to spend money on a prompt can ask what it
 * will cost, and whether it busts a budget, *before* sending it. Every other
 * surface here answers that for a human after the fact — a CLI you run, a page you
 * paste into, a check that fails a build. This answers it for the thing actually
 * composing the prompt.
 *
 * **It runs on the caller's machine and costs this project nothing.** One process
 * over stdio, spawned by whatever client wants it, exactly like the CLI. There is
 * no service to host, nothing to keep up, and no prompt leaves the machine. Worth
 * saying because "MCP server" reads like infrastructure and this is not.
