`POST /api/v3/gym/runs`. Post only runs whose verifier actually ran: a
score is a claim, and a crashed grader is not a grade.

If the dev server binds loopback only (another session started it
without `PHX_LISTEN_ALL`), bridge instead of fighting over the port: run
a forwarder from `0.0.0.0:4001` to `127.0.0.1:4000` and point the
adapter at it with `OPENAGENTS_CODER_API_URL=http://host.docker.internal:4001`.

Known constraint on Apple Silicon: Terminal-Bench task images are amd64,
and under qemu emulation the verifier's `uv`/`pytest` segfaults after the
agent phase completes. Enable Docker Desktop's Rosetta emulation
