Makefile

# Makefile — Thread Pool (no CMake required)
# Requires only: g++ (GCC 10+ or Clang 11+)
#
# Targets:
#   make                 — build tests + benchmark (Release)
#   make test            — build and run all tests
#   make bench           — build and run benchmark
#   make tsan            — build with ThreadSanitizer and run tests
#   make asan            — build with AddressSanitizer and run tests
#   make clean           — remove all build artifacts
