because it is already a generic PeftTrainer V2 worker.

The first milestone is intentionally small: run one trainer+rollout pipeline
step with `BETA=0.0` and `WEIGHT_SYNC_MODE=none`. Reference KL, Raiden weight
sync, agent-sandbox prewarming, and production DeepSWE-scale settings can be
layered on after the basic pipeline is stable.
step with `BETA=0.0` and `WEIGHT_SYNC_MODE=none`. The default path uses the
regular DeepSWE `SWEEnv` backend. Set `USE_AGENT_SANDBOX=1` to construct
`SWEEnv` with `SandboxFleet` inside the rollout worker process.

```bash
cd tunix/experimental/examples/deepswe_dist
BETA=0.0 WEIGHT_SYNC_MODE=none MAX_STEPS=1 BATCH_SIZE=1 NUM_GENERATIONS=2 ./launcher.sh
```
```

```bash
cd tunix/experimental/examples/deepswe_dist
USE_AGENT_SANDBOX=1 BETA=0.0 WEIGHT_SYNC_MODE=none MAX_STEPS=1 BATCH_SIZE=1 NUM_GENERATIONS=2 ./launcher.sh
```

For sandbox placement, set `SANDBOX_NAMESPACE`, `SANDBOX_NODE_SELECTOR_KEY`, and
`SANDBOX_NODE_SELECTOR_VAL` before launching. The launcher forwards them to the
rollout worker as the `agent_sandbox_rl` variables consumed by `SWEEnv`.
