- split quantize into quantize.cuh, templated on input type (bf16/fp16/fp32)
- rename pybind entry quantize_bf16 to quantize; validate the fmt enum
- fix fp8x2 packing: one 32-bit word packs two pairs (halves were dropped)
- drop the dead OutFp8 template param; GEMM output is always bf16
- fp8_state.reset() restores recipe/format defaults too (test state leak)
- rewrite tests for the two-primitive API with fp32-domain amax references
- K tile 32->64 (new default): fewer barriers, more MMA per stage; generalize tile_at swizzle and load_operand_tile accordingly
- 64x128 small-M CTA for m<=64 (2x at 64x4096x4096)
- L2 rasterization for crosswise-A layouts (+6..21%)
- micro-bench: NT 4096^3 +35%; linear fwd 1.24-1.76x, bwd 1.71-2.27x vs bf16
- add csrc/tests/fp8_test.cu (single MMA demo + GEMM layouts x K-tiles vs CPU reference)
