gpuwm-hex 0.3.1

gpuwm-hex 0.3.1

New:

• A fine hex core at any CONUS point, from HRRR. gpuwm-hex mesh-plan --point LAT,LON
  plans and prices the 937.5 m ladder and, with --generate, builds, admits, registers
  and culls it; gpuwm-hex intermediate --source hrrr and gpuwm-hex lbc write the
  intermediates and the boundary files.
• The surface/PBL cadence is a selectable knob: gpuwm-hex forecast --pbl-cadence SECONDS.
  The default stays the weld; a cadence that is not a whole number of steps is refused by name.
• Local time stepping reaches a limited-area cull (--local-timestep), selectable and off
  by default.
• The engine-verdict instrument ships in the tree (tools/measure_engine_verdicts.py); a
  re-pin is one command. An engine that is not on PyPI is admitted by a measured row of its
  sixteen seam bytes, and the door, doctor and the driver's checkout guard read that one row.
• A seam-level engine A/B (tools/measure_engine_seam_ab.py) and a per-kernel
  capture-and-replay instrument (tools/kernel_element_ab.py).

Fixed:

• Requires gpuwm 2.7.4. The sixteen seam pins are re-measured against the published wheel;
  the two files that moved since 2.7.3 do not reach the port's path, measured byte-neutral
  through the seam and on a one-hour point-cull forecast.
• The forecast step is faster on the 937.5 m point cull, 1.22x per step at the landed tree:
  the CUDA admission is measured once, every recovery kernel launches once, the health gate
  and the regional validations run on the device, and the level-independent dycore kernels
  launch one thread per element. Every history frame is byte-identical and the contract deck
  is 8 of 8 bitwise, dual-run identical.
• gpuwm-hex init stamps the run declarations a mesh-time capsule leaves absent, so the
  forecast driver no longer refuses a first point cull.
• The boundary producer resolves through the engine ladder, so a bundle staged by
  gpuwm fetch-bridges opens the lbc leg the way it opens init.
• The HRRR intermediate's map source fits the 32-character WPS field.
