Align with Advanced Llama 3.2 GRPO LoRA reference notebook pattern

Key changes to match the official Unsloth reference:
- 4 separate reward functions (format exact, format approx, action
correctness, environment-executing) instead of 1 combined
- lora_rank=64, lora_alpha=lora_rank (was r=16, alpha=32)
- learning_rate=5e-6 (was 5e-5, 10x off)
- Added: weight_decay=0.1, warmup_ratio=0.1, lr_scheduler_type=cosine,
optim=adamw_8bit, max_grad_norm=1.0
- num_generations=4 (was 2), max_steps=500 (was 300)
- max_seq_length=2048 (was 768)
- UNSLOTH_VLLM_STANDBY=1 env var for faster vLLM startup
- random_state=3407 for reproducibility
- tokenizer= instead of processing_class= (TRL 0.22.2 API)
- Pinned transformers==4.56.2, trl==0.22.2 in notebook
- save_steps=250 (was 50)
