fix(critical): match Sub168 config exactly + disable risky numerical patch

1. computility-run.yaml: restore Sub168's proven params:
   - max-model-len=256000 (not 100000)
   - gpu-memory-utilization=0.95 (not 0.90)
   - max-num-seqs=2 (not 1)
   - max-num-batched-tokens=4096 (restored)
   - enable-chunked-prefill (restored)
   These params worked for Sub168. Now that pip install is removed,
   they should work for us too.

2. patch_ops.sh: disable patch_numerical_stability.py
   If corex_gdn loads (which it should without pip install breaking deps),
   Python GatedDeltaNet fallback never runs, so numerical patches are
   unnecessary. Running regex replacements on qwen3_5.py risks breaking
   corex import conditions.
