/**
 * End-to-end coverage for an AMR (vela) chat run driven through the real
 * tools-dev orchestrated daemon. Boots a namespaced daemon + web pair,
 * configures it to spawn a self-contained fake `vela` binary, pre-seeds
 * `~/.amr/config.json` as if the user had already approved CLI login,
 * then drives a complete /api/runs lifecycle for `agentId: 'amr'` and
 * asserts the assistant message picks up the fake's canned text.
 *
 * What this proves that lower-tier tests don't:
 *
 *   1. The chat-run path in `apps/daemon/src/server.ts` correctly routes
 *      `agentId: 'amr'` through `attachAcpSession` (not the legacy
 *      json-event-stream parser the old `incongruous-megaraptor` branch
 *      used).
 *   2. The synthetic `'default'` model id is preserved so vela can use the
 *      upstream account default without an explicit `session/set_model`.
 *   3. The full ACP transport (`initialize` → `session/new` →
 *      `session/set_model` → `session/prompt` → `session/update*`) flows
 *      between the daemon and a spawned subprocess that respects vela's
 *      `~/.amr/config.json` resolution path.

//   `vela login`                        — write ~/.amr/config.json and exit 0.
