fix: use native Windows ARM64 binary for Bun >= 1.3.10 (#165)

Browse Source 
Bun v1.3.10 ships native Windows ARM64 binaries. Update
getArchitecture() and getAvx2() to be version-aware so that
windows-11-arm runners download bun-windows-aarch64.zip instead of
falling back to bun-windows-x64-baseline.zip. The x64 fallback is
preserved for older versions that lack ARM64 assets.

Closes #164
