Ruinan LiandClaude Fable 5 5b1f321847 [BugFix] Reject uncovered warp partitions in T.gemm instead of producing silently wrong results (#2724) ...

* fix: resolve issue 2537

* test: pin default-search regression tests to the MMA backend

On sm_90 SelectInst reroutes M>=64 / warps%4==0 shapes to the WGMMA
search, so two tests written against the default search exercised the
wrong code path on Hopper CI. The FullCol M=192 N=104 numeric test
additionally hit a pre-existing, partition-independent WGMMA
descriptor-layer limitation (N=104 fits no canonical GMMA swizzle atom).
Pin both to the MMA path via tl.disable_wgmma; the WGMMA search keeps
its own dedicated tests.
