The -march=x86-64-v3 flag requires AVX2 instructions which are not available on all target machines (e.g. QEMU VMs with only SSE4.2). This caused 'Illegal instruction' crashes at runtime. Remove the explicit -march flags from both build and release workflows to use the default target architecture, ensuring the .deb package runs on a wider range of x86-64 machines.
