#!/usr/bin/env bash
# build.sh — build static uc binaries for all targets
#
# Produces fully static, zero-dependency binaries:
#   dist/uc-aarch64-apple-darwin      (macOS Apple Silicon)
#   dist/uc-x86_64-unknown-linux-musl (Linux x86_64, static)
#
# Requirements:
#   - mise (manages rust toolchain)
#   - zig + cargo-zigbuild (for Linux cross-compilation)
#   - rustup target x86_64-unknown-linux-musl (one-time setup)
#
# Usage:
#   ./build.sh              build all targets
#   ./build.sh macos        build macOS only
#   ./build.sh linux        build Linux only
