[CLEANUP] Remove 13 dead patch scripts — only 1 remains (transformers registration)

Removed (replaced by full-file cp in patch_ops.sh):
  - patch_model_runner.py → replaced by model_runner.py (1932 lines)
  - patch_xformers_sdpa_seq.py → replaced by xformers.py (901 lines)
  - patch_xformers_sdpa_seq_kernel.py → was unused
  - patch_xformers_sdpa_batch.py → was unused
  - patch_xformers_sdpa_batch_kernel.py → was unused
  - patch_vllm_qwen3_5.py → replaced by registry.py (455 lines)
  - patch_vllm_tool_parser.py → replaced by tool_parsers_init.py
  - patch_enable_triton.py → was unused
  - patch_head256_triton.py → was unused
  - patch_ixformer_native.py → was unused
  - patch_paged_attention_v2.py → was unused
  - patch_triton_tuning.py → was unused
  - patch_vectorized_decode.py → was unused

Remaining: patch_transformers_qwen3_5.py (1 script, unavoidable — modifies
pip-installed transformers which is version-specific)

Architecture: 13 blind string-replace scripts → 0. All base modifications
are now full-file replacements with complete source context.
