/**
 * dispatch-external-tool-command — the HOST supervisor for the out-of-process
 * external tool COMMAND dispatch plane (ADR-0054, increments M4-C / M4-D / M4-E).
 *
 * For an EXTERNAL-provenance tool command (installed / project-local /
 * user-global), the host forks the {@link executeToolCommandWorker} entry
 * instead of importing + running the handler in-process. The worker imports the
 * untrusted runtime and runs the handler; this supervisor:
 *
 *   1. marshals the minimal serializable {@link ToolCommandWorkerSpec} to a temp
 *      file and forks the worker entry via the shared {@link runWorkerSpec}
 *      fork/IPC core, which turns a child throw / `process.exit` / crash /
 *      premature-exit / fork-failure into a structured parent-side rejection,
 *      enforces the wall-clock timeout, serves the worker's host-RPC upcalls
 *      against the REAL host {@link ToolCliContext}, and inherits run correlation
 *      through the child env;
 *   2. on success, replays the slim {@link ToolCommandResult} through the REAL
 *      host seams (`render` / `emitEnvelope` / `emitJson` / `emitRaw` /
 *      `emitError` / `setExitCode`) so the output contract stays byte-identical
 *      to the in-process path.
 *
 * Bundled first-party tools never reach here — they stay in-process (the trusted
 * computing base). External tools have NO in-process fallback by trust tier
 * (ADR-0054): a fork failure is a hard, structured error, not a silent in-host
 * run.

 *
