M1 of AMD support. Adds a ROCm build job to the dev pipeline modeled on upstream's ubuntu-22-rocm and our linux-x64-cuda job: installs ROCm 7.2.1 from repo.radeon.com, builds with GGML_HIP + rocWMMA flash-attn for RDNA targets only (gfx1030/1100/1101/1102/1151/1200/1201 — GCN/CDNA excluded by scope, those users use Vulkan), bundles libggml-hip.so plus the HIP runtime and rocBLAS/hipBLASLt Tensile data so the archive is self-contained. Build-only: no AMD GPU on the runner, the backend is a dlopen'd plugin (GGML_BACKEND_DL). Also adds the pre-existing linux-x64-cuda-13.3 to the dev-latest EXPECTED list (was missing). Kernels are already RDNA-aware (mmvq-tq.cu). Real-hardware validation (test-backend-ops on gfx1151/gfx1100) is the next milestone.
dev-build.yml alone only puts ROCm in dev-latest; add the same job to release-turboquant.yml (needs: verify-version) and to publish-release's needs list so tagged releases carry llama-turboquant-linux-x64-rocm. Same recipe as the dev-build job — RDNA-only gfx targets, HIP runtime + Tensile data bundled.
ci: linux-x64-rocm (HIP) backend build AMD support
…s the release publish-release had no if:always(), so one failed backend build (e.g. the new ROCm job) would skip publish entirely and ship NOTHING. Add if:always() gated on verify-version, publish whatever archives exist, and list any missing backends in the notes (mirrors publish-dev-latest). Also add the linux CUDA and ROCm rows to the notes table (CUDA was missing).

Cuts the AMD/ROCm minor release.
ROCm is build-validated in CI; real-hardware validation (test-backend-ops on gfx1151/gfx1100) is the next milestone. Windows ROCm is not included (toolchain WIP).
