Run the test suite on Windows in CI

[yemine0x01]

Depends on #108 and #109. Their commits are included here until they merge.

@yemine0x01 Thanks for this — it's a clean, well-scoped change: the _julia_string escaping (backslashes/quotes/$) is exactly right for Windows paths, it carries a Google-style docstring + type hint, and the new test_correct_network.py covers the tricky cases (quoted dirs, $HOME) with a real round-trip.

What's needed

• Dependency ordering: you note this builds on Flush the C runtime on Windows when redirecting solver output #108 and Escape paths passed to Julia when correcting a network #109. Since their commits are folded in here, this PR shouldn't merge before they do — a maintainer will want to sequence that.
• Checks: CI (incl. the new windows-pytests job) is still running. Worth confirming the Windows job goes green before merge, since that's the whole point of the PR.
• Reviewer: per CONTRIBUTING, please add Alban Puech as a reviewer if not already.

No docstring/type-hint/print gaps on my read, and no new deps or config params, so the pyproject.toml/YAML/docs steps look N/A here. Deferring the merge call to a maintainer.

@yemine0x01 Thanks for pulling in main — the branch is now current (mergeStateStatus went from needing a rebase to UNSTABLE, i.e. just waiting on checks), so that point is cleared.

Quick status on the rest:

• Checks: the merge kicked off a fresh run. pre-commit and security-test are green; windows-pytests, pytests, dynamic-pytests and CodeQL are still running. Worth a glance that windows-pytests lands green, since that's the point of the PR.
• Dependency ordering: Flush the C runtime on Windows when redirecting solver output #108 and Escape paths passed to Julia when correcting a network #109 are both still open, and this PR folds in their commits — so it shouldn't merge ahead of them. A maintainer will want to sequence that.
• Reviewer: no reviewer is requested yet — per CONTRIBUTING, please add Alban Puech.

Nothing in the merge introduced new issues on my read. Deferring the merge call to a maintainer.
