5// only correct for one platform — instead we detect the host and

8// Lookup order (redundant by design; any one succeeding is enough):

9// 1. Cached install under node_modules/yaver-cli/hermesc/<key>/hermesc

10// 2. Per-user cache under ~/.yaver/hermesc/<key>/hermesc

11// 3. Download from the react-native npm tarball and extract just
