- Replace `.filter(...)[0]` with `.find(...)` in chooseBestManifest to short-circuit search and avoid array allocations. - Hoist nodeLockfiles constant array outside chooseBestManifest function scope. - Replace chained `.filter().filter()` with `.some()` in shouldSkipAddingFile. - Avoid transient inline array allocations in detectProjectTypeFromFile.

⚡ Bolt: Optimize manifest selection and file filtering in find-files
💡 What:
Array.prototype.filter(...)[0]withArray.prototype.find(...)across all project type manifest matchers inchooseBestManifest.nodeLockfilesarray outside ofchooseBestManifestso it is not re-created on every function call..filter().filter()and.lengthcheck inshouldSkipAddingFilewith.some()to short-circuit upon first match and avoid intermediate array allocations.['yarn', 'npm', 'pnpm'].includes(...)indetectProjectTypeFromFilewith direct string comparison checks.🎯 Why:
During directory scanning with
find(),chooseBestManifest,shouldSkipAddingFile, anddetectProjectTypeFromFileare called repeatedly for every directory and manifest file discovered.Using
.filter()creates full temporary arrays even when only the first matching element is needed. Using.includes()on transient arrays allocates array instances on every single invocation in hot loops.📊 Impact:$O(N)$ full iterations to $O(1)$ / $O(M)$ short-circuiting lookups per directory.
Eliminates unnecessary temporary array allocations during directory scanning and reduces list searching overhead from
