Subject: [PATCH] perf(storage): parallelize sequential file reads in
 onFileDrop

Refactored the sequential `for...of` loop over `event.payload.paths` in `onFileDrop` to use `Promise.all` with `paths.map`, executing `invoke("read_text_file", ...)` concurrently. This resolves the performance bottleneck where reading multiple dropped files was artificially serialized.
