# Cosmopolitan build for King Discord bot
# Produces an Actually Portable Executable (APE)
#
# Usage:
#   make          — builds the 'king' APE binary (auto-downloads cosmocc)
#   make test     — builds and runs tests
#   make lint     — runs clang-format and clang-tidy checks
#   make clean    — removes build artifacts
#   make distclean — also removes downloaded cosmocc toolchain
