 - We add a release contract, `pixi run -e py312 test-release-contract`, that
   compares `feols` / `fepois` / `feglm` / `quantreg` against pyfixest 0.60.0.

+- The `benchmark` environment now declares its CUDA 12.8 requirement on a named
+  platform, because pixi has deprecated the `[system-requirements]` table. We
+  also refresh `pixi.lock` in the newer v7 format. Both ask for pixi 0.71.0 or
+  newer.
