#   scripts/test.sh                          # Auto-detect everything
#   scripts/test.sh --arch x86_64            # Force x86_64 build
#   scripts/test.sh CC=gcc-14 CXX=g++-14    # Override compiler
#
# This script is the SINGLE source of truth for running tests.
# Used identically in local development and CI workflows.
