/**
 * Single-target Bun compile helper. Must be run with Bun on PATH:
 *   bun tools/release/lib/binary-compile.mjs --entry <path> --outfile <path> --target <bun-target>
 *
 * Uses `bun build --compile` (CLI). The Bun.build({ compile }) API on ≤1.2.19
 * can exit 0 without writing outfile; CI pins 1.2.19 so we stay on the CLI.
 *
 * Called by binary-build.mjs (Node orchestration stays on Node).
