fix: Configure Faiss with SVE optimization for ARM64 builds

Browse Source 
- Set FAISS_OPT_LEVEL to "sve" for ARM64 architecture
- Disable x86-specific SIMD instructions (AVX2, AVX512, SSE4.1)
- Use ARM64-native SVE optimization as per Faiss conda build scripts
- Add architecture detection and proper configuration messages

Fixes compilation error: "xmmintrin.h: No such file or directory"
on ubuntu-24.04-arm runners.
