2025 changelog tracker

[ev-br]

Testing 2025.12 features in CI is a bit of chicken-and-egg, so we need to test locally first, make the array-api-strict release, and then polish the tests. This issue is to track the first step: make sure array-api-strict has all the features, and they have been tested locally.

A checked box means it's been tested with --max-examples 10_000 vs array_api_strict main branch.
