Download ArWen 2.9.2

ArWen 2.9.2 is a release on the 2.9 line. The desktop stays ArWen Desktop 1.0.10, from the 2.9.0 release.
- Install or upgrade: pip install --upgrade "gpuwm[all-cu12]==2.9.2".
- Integration kit, verification records, and checksums.
- Node GPU gate: Stage 1 and both GPU-shard results, with the tested source revision and card identity.
New
- A gpuwm-hex run can be the initial and boundary source of an ArWen domain.
- Observation readers: Himawari AHI, GK-2A AMI, GOES-18 full disk and CONUS, with one geostationary fetcher.
- MADIS public streams (aircraft, sondes, mesonets, live feed) in the observation doors.
- A GLM flash-extent-density reader.
- European radar: live and archive feed listings (FMI, DMI), dual-PRF velocity correction and DWD split volumes.
- Radar readers for JMA, IRIS RAW, UF, CfRadial and DORADE, with open-archive fetch by table.
- The run timeline records the measured cores of every stage, and a single-core gate fails a stage that holds one core while the card or other cores wait.

Fixed
- Every fix in 2.9.1.
- Thompson microphysics (mp_physics = 8) runs straight after pip install gpuwm: the first run downloads and checks its two large lookup tables.
- MPAS mesh generation no longer triangulates on a single thread.
- Later forcing times in preparation are built side by side.
- The hex vertical grid writes its output in parallel.
- Lower GPU memory for WSM6, the MPAS column seam, the batched shortwave chain and New Tiedtke in the MPAS column batch.
- A missing static dataset is refused once, naming every dataset the native static builder opens.
- US 00Z soundings from MADIS are dated to their real release time.
