Makefile.cbm

# Makefile.cbm — Build system for pure C rewrite
#
# Usage:
#   make -f Makefile.cbm test           # Build + run all tests (ASan + UBSan)
#   make -f Makefile.cbm test-foundation # Foundation tests only (fast)
#   make -f Makefile.cbm test-tsan      # Thread sanitizer build
#   make -f Makefile.cbm cbm            # Production binary
#   make -f Makefile.cbm clean-c        # Remove build artifacts

# Compiler selection — override via: make CC=gcc CXX=g++
# macOS: cc (Apple Clang) — universal binary with ASan support
# Linux: gcc/g++ — system default with full sanitizer support
# CI scripts pass CC/CXX explicitly; don't rely on defaults here
