Subject: [PATCH] ci: Add Windows ARM64 build and test support

## Description

Add support for building and testing Windows ARM64 (aarch64-pc-windows-msvc) binaries in CI workflows.

Changes:
- Add `aarch64-pc-windows-msvc` target to build matrix in `rust.yml` for testing
- Add `aarch64-pc-windows-msvc` target to build matrix in `release.yml` for releases
- Skip runtime tests for Windows ARM64 (cross-compiled target, cannot run on x86_64 runners)
- Update release installation instructions to include Windows ARM64 download option

Windows ARM64 binaries will be built on Windows runners using cross-compilation and included in releases alongside x86_64 Windows binaries. This enables support for ARM64 Windows devices such as Surface Pro X and Windows on ARM systems.
