Remote runs exec the repo-relative manifest python via bash with no
existence check ('vendor/trellis2-mlx/.venv/bin/python: No such file'),
killing trellis2_mlx on the validated m1 lane (its fork lives at
~/trellis2-mlx). Both run.py launchers are stdlib-only and already
resolve the per-box fork checkout + venv themselves — run them on the
server/system python instead. trellis_mac/run.py now resolves its vendor
venv explicitly (sys.executable was only correct under the old pin).
