[devin-ai-integration]

Why I did it

Upgrade the SAI API version from 0.9.4 to 1.12 across multiple platform files to support newer SAI features and compatibility.

How I did it

Updated SAI version definitions in the following files:

1. SAI_VER updates (0.9.4 → 1.12):

   • platform/vs/libsaithrift-dev.mk
   • platform/mellanox/libsaithrift-dev.mk
   • platform/barefoot/libsaithrift-dev.mk

2. Vendor-specific SAI implementation versions:

   • platform/mellanox/mlnx-sai.mk: SAIBuild2505.33.0.10 → SAIBuild2505.1.12.0
   • platform/nvidia-bluefield/recipes/dpu-sai.mk: SAIBuild0.0.45.0 → SAIBuild1.12.0.0
   • platform/components/docker-gbsyncd-broncos.mk: 3.12 → 1.12

3. SAI Redis adapter: rules/sairedis.mk: 1.0.0 → 1.12.0

4. Dockerfile comments: Updated SAI version references in build container templates

How to verify it

Build the SONiC image for affected platforms and verify SAI packages are correctly versioned.

⚠️ IMPORTANT - Human Review Required:

• Verify MLNX_SAI_VERSION (SAIBuild2505.1.12.0) is the correct SAI 1.12-compatible version from Mellanox/NVIDIA
• Verify DPU_SAI_VERSION (SAIBuild1.12.0.0) is the correct SAI 1.12-compatible version for Bluefield DPU
• Verify LIBSAI_BRONCOS_VERSION change (3.12 → 1.12) - this appears to be a version downgrade and may be incorrect
• Confirm packages exist at the constructed download URLs
