v1(ci): use uv inline-scripting, prevent concurrent runs in macos-integration-tests GHA

[ndonkoHenri]

Summary by Sourcery

Switch CI pipelines to use uv's inline scripting and add concurrency safeguards to the macOS integration workflow

Enhancements:

• Switch CI uv run/build commands to inline scripting by removing explicit --with plugin flags in AppVeyor scripts
• Configure GitHub Actions macOS integration tests to only trigger on relevant path changes and cancel in-progress runs for the same branch
• Simplify Python-based CI helper scripts by removing redundant file mode arguments when opening files

What does github.ref mean here?

[ndonkoHenri]

${{ github.ref }} is a GitHub Actions context variable that contains the full ref (reference) of the branch or tag that triggered the workflow. For example, for a branch it could be refs/heads/v1-improve-gha, and for a tag it could be refs/tags/v1.0.0. This is used to group workflow runs by branch or tag for concurrency control.

[FeodorFitsner]

OK, so it's per branch. Understood.

[ndonkoHenri]

just from modifying the group name again to prevent duplicate runs when pushing a commit to a branch which has an opened PR.

Now in such cases, only the PR run will take the lead, and the branch run will be cancelled.
