bb7b2f40fc Add support for QAT + LoRA (#2976) 
**Summary:** Quantization-aware training (QAT) helps mitigate
quantization degradation by simulating quantization numerics
in high precision during training (fake quantization). This PR
combines QAT with LoRA by applying torchao's QAT support to
the peft model.

See the following for more details:

- torchao QAT: https://github.com/pytorch/ao/blob/main/torchao/quantization/qat/README.md
- torchtune QAT + LoRA: https://dev-discuss.pytorch.org/t/speeding-up-qat-by-1-89x-with-lora/2700

Current QAT schemes supported are:

```
fp8-fp8, targeting the torch.ops.fbgemm.f8i4bf16_shuffled kernel
fp8-int4, targeting the torch.ops.fbgemm.f8f8bf16_rowwise kernel
```

**Test Plan:**

```
from unsloth import FastLanguageModel

lora_rank = 32

model, tokenizer = FastLanguageModel.from_pretrained(
    model_name = "unsloth/Qwen3-4B-Base",
    max_seq_length = 2048,
    load_in_4bit = False,
    fast_inference = False,
    max_lora_rank = lora_rank,
)

model = FastLanguageModel.get_peft_model(
    model,
    r = lora_rank,
    target_modules = [
        "q_proj", "k_proj", "v_proj", "o_proj",
        "gate_proj", "up_proj", "down_proj",
    ],
    lora_alpha = lora_rank*2,
    use_gradient_checkpointing = "unsloth",
    random_state = 3407,
    qat_scheme = "fp8-fp8",
)

lora.Linear(
  (base_layer): FakeQuantizedLinear(
    in_features=2560, out_features=4096, bias=False
    (activation_fake_quantizer): FakeQuantizer(Float8FakeQuantizeConfig(dtype=torch.float8_e4m3fn, granularity=PerRow(), hp_value_lb=None, hp_value_ub=None))
    (weight_fake_quantizer): FakeQuantizer(Float8FakeQuantizeConfig(dtype=torch.float8_e4m3fn, granularity=PerRow(), hp_value_lb=None, hp_value_ub=None))
  )
  ...
)
```

ea4b7c2c6b Update install instructions for latest vLLM release (#3175) 
1. Removed the `--extra-index-url https://wheels.vllm.ai/nightly` from the uv install instructions because this causes it to crash; Removing that flag solves the issue and is more stable overall. Tested with RTX 5090 CUDA 12.8 on Linux. 

2. Removed `uv pip install -U triton>=3.3.1` because triton 3.3.1 is already installed with the vllm command.
