add windows arm64 wheel builds

[joe-clickhouse]

Summary

• Adds a Windows ARM64 wheel build to the release pipeline so Windows on Arm installs a binary wheel from PyPI instead of falling back to a source build.
• Builds natively on the windows-11-arm GitHub-hosted runner.
• Covers CPython 3.10 through 3.14, including the free-threaded 3.14 build. PyPy is excluded because there is no PyPy for win_arm64.

Closes #785

Pull request overview

Findings (ordered by severity)

• No confirmed correctness issues found in the diff. The changes are limited to release automation configuration and a CHANGELOG entry.
• Residual validation gap: I can’t fully validate CI runner availability/behavior (e.g., the windows-11-arm hosted runner label and toolchain support for all targeted Python versions) from the repository contents alone; this is best confirmed by running the workflow (or a publish_type=build dry run) on the target runner.

Purpose

Adds Windows ARM64 (win_arm64) wheel builds to the release workflow so Windows on Arm can install binary wheels from PyPI instead of building from source.

Changes:

• Add a dedicated GitHub Actions job to build Windows ARM64 wheels via cibuildwheel on a Windows ARM runner.
• Include the new ARM64 wheel artifact in the publish job’s dependencies.
• Document the improvement in CHANGELOG.md.
