Replace O(n²) linear searches with O(1) hash set lookups when checking if a dependency is in the requested deps list. Previously, isRequestedDep() was called inside nested loops, doing a full stream().anyMatch() scan for every dependency and child dependency, causing long delays on large dependency graphs. Now creates a Set<String> lookup cache at the start of parseDependencies() and uses constant-time contains() checks instead of linear scans.
