Add Windows ARM64 release artifact

[thisislvca]

Summary

• Add a Windows release matrix that builds both the existing x64 portable zip and a new native ARM64 portable zip.
• Publish Mouser-Windows-arm64.zip as a GitHub Release asset alongside the existing platform artifacts.
• Update English and Chinese download docs to list the Windows x64 and Windows ARM64 assets separately.
• Use a short pip temp directory only for the Windows ARM64 job because hidapi currently builds from source there.

Refs #134.

Validation

• actionlint .github/workflows/release.yml
• YAML parse of .github/workflows/release.yml
• git diff --check
• .venv/bin/python -m py_compile main_qml.py core/*.py ui/*.py
• .venv/bin/python -m unittest discover -s tests -p 'test_*.py'
• QML lint using the repo CI command
• Manual Release workflow run on windows-arm-support: https://github.com/TomBadash/Mouser/actions/runs/25140432906

Artifact check

Downloaded the Mouser-Windows-arm64 artifact from the latest manual Release run. The zip is 44 MB, contains Mouser/Mouser.exe, and the executable is detected as PE32+ executable (GUI) Aarch64, for MS Windows.

Notes for testing

This PR is still draft because the remaining validation needs an actual Windows ARM64 machine. A tester should download the Mouser-Windows-arm64 artifact from the manual Release workflow run and confirm Logitech device detection, button remapping, gestures, tray behavior, and startup settings.
