Detailed Description

POD parameter blocks for the warp-register predictor policies.

Shared VERBATIM between the device policies (warp_fusion.cuh, which using these) and the host predictor stages that pack these bytes into the fused params blob (which the generated kernel reinterpret_casts). Keep them plain POD and dependency-free (no device code), so both the host stage compile (g++) and the device compile (nvcc / NVRTC) agree on the layout — the LC-of chunk_op_params.h.

CONVENTION: every warp predictor's Params begins with float inv2eb at offset 0. The predictor stage cannot know the error bound (the quantizer owns it), so it packs 0 there; the generic runner overwrites those 4 bytes with 1/(2*abs_eb) resolved from the primed quantizer bound before uploading the blob.
