Add vLLM v0.18.1 source tree with KV transfer abort fix

third_party/vllm/ now tracked in git for direct patch management.
Based on vLLM v0.18.1 release with one patch applied:

  vllm/v1/core/sched/scheduler.py:
    Replace fatal assert with graceful skip when KV transfer callback
    arrives for an already-aborted request during PD disaggregated serving.

Future vLLM modifications should be made directly in third_party/vllm/
and committed normally. The patches/ directory is kept as documentation
of what changed from upstream.

# Disaggregated Prefill V1
This example contains scripts that demonstrate disaggregated prefill in the offline setting of vLLM.
## Files
- `run.sh` - A helper script that will run `prefill_example.py` and `decode_example.py` sequentially.
- Make sure you are in the `examples/offline_inference/disaggregated-prefill-v1` directory before running `run.sh`.
- `prefill_example.py` - A script which performs prefill only, saving the KV state to the `local_storage` directory and the prompts to `output.txt`.
- `decode_example.py` - A script which performs decode only, loading the KV state from the `local_storage` directory and the prompts from `output.txt`.
