Optimize HTML5 file drop to parse files in parallel

Browse source 
Replaced the sequential `for...of` loop with `Promise.all` for reading dropped files via the HTML5 File API. Previously, when multiple files were dropped, the application awaited each file's `text()` promise sequentially, causing unnecessary delays. Parallelizing this provides a significant speedup for large batches of files.
