Rebuild for python 3.14 and 3.14t

Preempt the migrator because it won't do the nogil variant anyway. Follows conda-forge/numpy-feedstock#363

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

• ℹ️ The recipe is not parsable by parser conda-souschef (grayskull). This parser is not currently used by conda-forge, but may be in the future. We are collecting information to see which recipes are compatible with grayskull.
• ℹ️ The recipe is not parsable by parser conda-recipe-manager. The recipe can only be automatically migrated to the new v1 format if it is parseable by conda-recipe-manager.

We're back to the undiagnosed hangs on windows (also occurring in #250)

[h-vetinari]

OK, it seems I finally caught all potential sources of hangs. But we still get pretty catastropic test failures (see below).

In all cases that I've looked at, the hanging and failing runs were on older CPUs with

  "SIMD Extensions": {
    "baseline": [
      "SSE",
      "SSE2",
      "SSE3"
    ],
    "found": [
      "SSSE3",
      "SSE41",
      "POPCNT",
      "SSE42",
      "AVX",
      "F16C",
      "FMA3",
      "AVX2"
    ],
    "not found": [
      "AVX512F",
      "AVX512CD",
      "AVX512_SKX",
      "AVX512_CLX",
      "AVX512_CNL",
      "AVX512_ICL"
    ]
  }

whereas all the passing runs have

  "SIMD Extensions": {
    "baseline": [
      "SSE",
      "SSE2",
      "SSE3"
    ],
    "found": [
      "SSSE3",
      "SSE41",
      "POPCNT",
      "SSE42",
      "AVX",
      "F16C",
      "FMA3",
      "AVX2",
      "AVX512F",
      "AVX512CD",
      "AVX512_SKX"
    ],
    "not found": [
      "AVX512_CLX",
      "AVX512_CNL",
      "AVX512_ICL"
    ]
  }

So either there's something going wrong with the feature detection and we're trying AVX512 instructions on CPUs that don't support them, or the fallback code is buggy.

Here's the remaining failures, which look like things going completely haywire (not just minor tolerance violations). It's interesting though that - even despite the skips - there's only a handful of them.

test_solve_continuous_are rings a bell to me as a frequent source of flakiness in the main repo. The others not so much.
