Fix incremental panic

Summary:
This should fix facebook#199

Unfortunately the issue is not easily reproducible, but I'm fairly certain
I understand what is happening (we're mixing type values coming from
incompatible versions of the same module, and getting arity mismatches)

The only reported panic caused by this happens in `subset`, so we can just
make this robust. The only obvious way to deal with it is to say that if arities
mismatch, then the two classes are from different versions of the code and
for now they are not linearly orderable (trying to do anything else is tricky
because we'd have work out downstream logic).

Increase timeout for extension test

Summary:
test_extension is sometimes failing: https://github.com/facebook/pyrefly/actions/runs/14940864076/job/41977764460.

The failure message says that we're hitting a timeout of 2000 ms. The test seems happy after I increased the timeout to 5000 ms: https://github.com/rchen152/pyrefly/actions/runs/14940926912/job/41977931542.

Bump patch version

Summary:
Two days ago, we restructured the typeshed directory used in Pyrefly's
build.

This means it is not possible to run mypy_primer without a lot of extra
flags, because the defualt behavior is to compare the latest release vs
trunk for a typechecker, and one or the other is going to panic (because
the build scripts are coupled to the directory layout).

Triggering a patch version bump because there are no major changes, we
just need a tag to exist so mypy_primer can find it.
