glm5-fp8-mi355x-sglang-disagg: bump to v0.5.12.post1 image and patch DSA state-index path

amd-master.yaml
  - Image: rocm/sgl-dev:sglang-0.5.9-rocm720-mi35x-mori-0402
        -> lmsysorg/sglang-rocm:v0.5.12.post1-rocm720-mi35x-20260523
    (matches qwen3.5-fp8-mi355x-sglang-disagg; the older 0.5.9 image is
    no longer the reference build for hybrid-attention disagg models on
    MI355X.)
  - Scenarios: collapse the four legacy "top/middle/bottom/small-scale"
    search-spaces per ISL into a single 1P+1D TP=8 EP=1 dp-attn=false
    entry with the standard conc-list [8, 16, 32, 64, 128, 256, 512]
    for both 1k1k and 8k1k. dp-attn=false avoids the
    fused_moe_triton/layer.py:209 shared-slot assertion that
    --enable-dp-attention + --moe-a2a-backend mori triggers for GLM-5
    (256 routed + 1 shared expert; (256-1) % 8 = 7 != 0). The collapsed
    layout mirrors the qwen3.5-fp8-mi355x-sglang-disagg shape so the
    same CI matrix-expansion logic applies to both.

patches/mori_conn.py
  - Add patch #4: rank + length normalization in
    MoriKVReceiver._send_swa_dsa_state, immediately before the
    group_concurrent_contiguous call. For GLM-5 (single DSA component),
    upstream hands dst_state_indices as a 2-D (1, N) array while
    src_state_indices is 1-D length 1; the existing [:common_len]
    slice operates only on the outer axis, leaving the rank mismatched.
    np.diff then produces (1, N-1) vs (0,), which can't broadcast and
    crashes with "operands could not be broadcast together with shapes
    (1,12) (0,)". The fix ravels both indices to 1-D and re-truncates
    to common length so np.diff outputs compatible 1-D arrays. One-shot
    log gates the warning to once per receiver class.

  - Verified end-to-end:
      glm5-fp8-mi355x-sglang-disagg gsm8k flexible-extract = 0.9704 +/- 0.0047
      glm5-fp8-mi355x-sglang-disagg gsm8k strict-match     = 0.9712 +/- 0.0046
      qwen3.5-fp8-mi355x-sglang-disagg gsm8k (regression)  = 0.9780 +/- 0.004
    Patch #4 fires zero times on the Qwen3.5 Mamba path (it lives
    inside _send_swa_dsa_state, never called for Mamba); patches #1-#3
    behavior is unchanged.
