intent(asyncMap): tighten doc and test based on coderabbitai review feedback
decision(asyncMap-doc): explicitly note that workers are not cooperatively cancelled after a rejection — sibling workers keep claiming indices
decision(asyncMap-test): replace timing-sensitive `peakActive > 1` with exact `=== 4` — workers spawn synchronously via Promise.all so the cap is hit deterministically

intent(empty-dir-check): protect very large repos from FD exhaustion that unbounded Promise.all could trigger
rejected(p-limit): user wants to keep dependencies minimal — built a small in-tree helper instead
decision(asyncMap): single mapWithConcurrency helper rather than a p-limit-style limiter object — only call site is array map
decision(concurrency-limit): 20 in flight — well above libuv default thread pool (4) while still bounded for users who tuned UV_THREADPOOL_SIZE
