Adds sysctl hw.optional.arm64 check before uname -m checks to correctly detect Apple Silicon Macs even when shell runs under Rosetta 2 translation. Problem: uname -m returns x86_64 when terminal runs under Rosetta, causing installer to download x86_64 binaries instead of native arm64 binaries. Solution: Check sysctl hw.optional.arm64 on macOS first, which returns 1 on Apple Silicon regardless of Rosetta state. Tested: Correctly installs arm64 binaries on M2 Mac, no AVX warnings.

Hi Jaime @jpillora , thanks for your work!
Adds sysctl hw.optional.arm64 check before uname -m checks to correctly detect Apple Silicon Macs even when shell runs under Rosetta 2 translation.
Problem: uname -m returns x86_64 when terminal runs under Rosetta, causing installer to download x86_64 binaries instead of native arm64 binaries.
Solution: Check sysctl hw.optional.arm64 on macOS first, which returns 1 on Apple Silicon regardless of Rosetta state (run only on Mac).
Tested: Correctly installs arm64 binaries on M2 Mac, no AVX warnings.
