Fix CI

[ShantanuKodgirwar]

@roflmaostc Made some more changes to make this testing friendly with CI. Also did some dry runs to make sure this works properly. Some of the specifics:

• Some CI infra changes such as installation issues, updated to the latest version of uv in test.yml, added a workflow_dispatch trigger for manual (dry-)runs, and expanded testing coverage to 3.11–3.13.
• An additional test added that generates a minimal simu.hdf5 file so few other tests can run without a full dataset present in the repo.
• Also took care of few warning messages which weren't so important
• The test badge has a correct URL (it didn't earlier)

CI seems to pass but not testing anything.

So infrastructure works but it's not calling the test, is it?

[ShantanuKodgirwar]

That's not true. Click on the three dots ... and under view details > check "Run tests". There are however some tests that I have flagged to skip, these need some work and come from some legacy implementations.

Ah lol. How small is the dataset that it takes only a few seconds?

13 passed, 20 skipped in 6.09s

Also the skipped tests are normal? -> ok you answered

[ShantanuKodgirwar]

As of now most of them are small sanity (smoke?) tests mainly taken from whatever was scattered at the package level from the developers + pytest around it. However, there are few reconstruction tests under tests/Engines, but not extensive to cover all use cases. This is some work and I'll need to do that separately. There are a lot of implementations that must be looked at closely for that as well.
