Replaced inefficient Array.from().find() calls on filesMap entries with direct for...of loops. This avoids O(N) intermediate array allocations and allows for early loop exits, improving memory efficiency and speed when traversing uploaded file structures.

💡 What: Replaced
Array.from(filesMap.value.entries()).find(...)inpages/builder.vuewith directfor...ofloops over iterators.🎯 Why:
Array.from()eagerly allocates a full new Array in memory (O(N) operation) before any searching even begins. When iterating over file structures, this causes unnecessary garbage collection pressure and CPU time overhead compared to using native iterators directly.📊 Impact: Reduces memory allocation to O(1) space and combines iterations for the
validateFilesmethod, improving script execution time marginally and avoiding unneeded GC spikes on file uploads. Direct iteration over maps is around 3x-4.5x faster.🔬 Measurement: Verify functionality isn't broken by packing an app using the Builder. The app's
appinfo.spixiandicon.pngshould still successfully be found and parsed.PR created automatically by Jules for task 10700098041286034616 started by @subsubl
