/**
 * Smoke test for --full-static builds.
 *
 * The fully-static artifact embeds its own PHP runtime from the bundled SDK, so
 * this exercises the parts of that runtime most likely to break: the module
 * globals set up during php_module_startup (pcre was where a musl/glibc thread-
 * local storage mismatch used to crash), plus the usual string/array/JSON paths.
 *
 * The output is a fixed token so both the x64 and arm64 workflows can compare
 * it exactly, regardless of the matrix PHP version installed on the runner.
