fix: restore pdfjs worker to .mjs and add mjs to webpack resolve extensions

claude · claude · commit 2d5100a658ef · 2026-06-04T17:21:11.000Z
pdfjs-dist v4 only ships .mjs worker files (no .js variants). the previous commit incorrectly changed the worker path to .mjs -> .js. reverted to pdf.worker.min.mjs and added .mjs to webpack resolve extensions in both dev and prod configs so webpack can locate the file. WCN-19
