feat(ci): use native runners for all platforms, drop QEMU/Rosetta

Replace cross-compilation with native runners:
- macOS x86_64: macos-13 (Intel) instead of Rosetta on macos-15
- Linux aarch64: ubuntu-24.04-arm instead of QEMU on ubuntu-24.04
- Windows ARM64: windows-11-arm (kept from previous commit)

Remove QEMU setup step and build_only logic since all platforms now
build and test natively.
