Research direction

Start with the linked Array API support matrix, then inspect array_api_compat/dask/array/linalg.py to verify which linear algebra functions are missing. Check the reported FFT noncompliance as well; done means the missing Dask functions are implemented and the relevant support gaps are resolved.

Written by the indexing model from the issue text.

Description

blocked by upstream

Currently dask is missing some functions in the linear algebra module, and the fft module is apparently noncompliant. I haven't double checked this list, but a list of unavailable functions is here: https://data-apis.org/array-api-compat/supported-array-libraries.html#dask.
There's already some work on implementing the missing function here, but no issue yet(at least that I can find)
