codegen: support arm64 as a development platform and build target on Windows 11 #4482
Description
The problem
Perry should support ARM architecture on Windows because the Windows ecosystem is shifting toward ARM-based devices, and developers expect their tools and apps to run natively, efficiently, and without emulation penalties.
Justifications:
- Growing market of ARM‑based Windows devices
- Performance and efficiency advantages
- Emulation using Prism is not a long‑term solution
- Developer expectations
- Cross‑platform consistency
- Future‑proofing
- Better user experience
Alternatives considered
None
Scope
Rough size estimate so we can triage:
- Small
- Medium
- Large

Implemented in #8027. The PR adds native Windows ARM64 host detection, explicit windows-aarch64 / windows-arm64 targets, architecture-correct MSVC/xwin/SDK lookup, ARM64 runtime ABI handling, release/npm artifacts, and a native windows-11-arm build-and-execute CI smoke. Local cross-validation produced a 4.6 MB IMAGE_FILE_MACHINE_ARM64 PE. No version bump.
