// Build the /docs-index.json bundle consumed by @crema/lexical-rag-ui at
// runtime. Thin wrapper — all engine logic lives in the lib's builder.ts;
// this file owns the per-app config (which arcadia-app docs to index and
// how to tag them).
//
// Run: npm run build:docs
//
// Allowlist is intentional. Excluded files are aspirational/stale and
// would poison answers (TODO lists, design docs for unshipped features,
// sub-app READMEs that aren't part of arcadia-core). To add a file,
// append to SOURCES below — don't auto-discover.
