test: fix windows init test on 32-bit runners

[lweyrich1]

Fixes #256

Problem

TestLibrary.test_initialize_windows assumes a 64-bit Python runtime, but it only patches sys.platform. On 32-bit runners (e.g. Arch Linux ARM 32-bit), sys.maxsize indicates 32-bit and the code correctly selects JLinkARM instead of JLink_x64, causing the test to fail.

Solution

Patch sys.maxsize in the 64-bit Windows test to explicitly model the intended runtime. The 32-bit variant is already covered by test_initialize_windows_32bit.

Testing

PYTHONPATH=. python -m unittest -q
