Chenjie Luo 87ea8babe1 Add HuggingFace PTQ pipeline to launcher (#1100) ...

### What does this PR do?

Type of change: New feature

Adds a HuggingFace PTQ pipeline to the launcher, replacing the old
`hf_ptq.sh`/`hf_ptq_local.yaml` approach with a cleaner wrapper around
`huggingface_example.sh`.

**Key changes:**

- **New `common/hf/ptq.sh`** — wrapper script that downloads the model
via `huggingface-cli` if needed, then delegates to
`examples/llm_ptq/scripts/huggingface_example.sh`
- **New `examples/Qwen/Qwen3-8B/hf_ptq.yaml`** — example config for
Qwen3-8B nvfp4 quantization, supports both Slurm and local Docker
- **Removed `common/hf_ptq/hf_ptq.sh`** and
**`examples/Qwen/Qwen3-8B/hf_ptq_local.yaml`** — replaced by the new
unified pipeline
- **Configurable Slurm time limit** — `SlurmConfig.time` field replaces
the hardcoded `"04:00:00"` in `build_slurm_executor`
- **Configurable Slurm partition** — `slurm_factory` now reads
`SLURM_PARTITION` env var (default: `batch`)
- **`--clean` flag** — new `launch.py` option to `git clean -xdf` the
examples directory before job submission
- **Package `modelopt_recipes/`** — added to the nemo_run packager
include list

### Testing

- Tested HF PTQ pipeline on Slurm with Qwen3-8B
