/**
 * Prove the compiled addon supports table and synchronous process creation-time reads.
 *
 * Unlike node-pty, this package ships a prebuilt `.node` at the same
 * `build/Release/` path node-gyp writes to, so neither a load nor a path check
 * can tell a stale prebuilt from a source build. pnpm patches the source tree
 * and leaves that prebuilt in place, which is how `ProcessDataFlag.CreationTime`
 * came to exist in `lib/index.js` on a binary that ignores flag 4 -- the gate
 * read true and every row came back without `creationTimeMs`.
 *
 * `supportedProcessDataFlags` is exported by the patched `addon.cc`, so its
 * presence is the binary's own answer. Shared by the Node and Electron probes
 * the way `node-pty-job-ownership.cjs` is.
