fix(CRITICAL): CoreXGDN interface mismatch + engine death protection

Three fixes for the three bugs in latest docker log:

1. corex_gdn.py REWRITTEN — interface now matches qwen3_5.py:
   OLD: CoreXGDN(num_heads, head_dim, layer_idx, chunk_size, eps)
   NEW: CoreXGDN(num_v_heads, num_k_heads, head_k_dim, head_v_dim, conv_kernel_size, layer_idx)

   OLD forward: (q, k, v, gate, beta, conv_state, temporal_state, attn_metadata)
   NEW forward: (hidden_states, attn_metadata, conv_state, temporal_state,
                  in_proj_qkv, in_proj_z, in_proj_b, in_proj_a,
                  conv1d_weight, A_log, dt_bias, norm, out_proj)

   Fixes: 'CoreXGDN.__init__() got unexpected keyword argument num_v_heads'

2. serving_chat.py — engine death protection for multimodal:
   When model has no multimodal_config, return 400 instead of passing image data
   to engine (which causes permanent AsyncEngineDeadError).

   Fixes: 'ValueError: You set image=0 but found 1 items'

3. patch_ops.sh — ALWAYS deploy our modules (base image has bugs):
   - qwen3_5.py: ALWAYS deploy (base has NaN)
   - corex_gdn/moe/fa2.py: ALWAYS deploy (base interface mismatch)
   - corex_fa2.py was MISSING from base → now deployed

corex_gdn.py — GatedDeltaNet fused kernel dispatch for BI-V100
Comp 168 log shows:
corex_gdn.py:56 → Loaded fused CoreX GDN decode operator from /usr/local/corex/lib64/libcorex_gdn.so
corex_gdn.py:228 → Using fused CoreX GDN prefill operator
corex_gdn.py:138 → Using fused CoreX GDN decode operator
GDN layers (4 of 36 attention layers in Qwen3.5) use a gated delta-rule
recurrence instead of standard attention. The key operations are:
prefill: chunked delta rule — per-chunk state accumulation
decode: single-step recurrent — S = decay * S + beta * (k^T @ v), out = q @ S
Both paths use ixformer for matmul via ix_bridge when available.
Key stability fix from real machine logs:
- ixformer matmul (ix_matmul / ix_bmm) requires fp16 input
- Gate clamping [-5, 0] prevents state explosion (decay only)
- State clamping ±100 prevents inf propagation
Interface matches qwen3_5.py expectations:
