v4.0.1 — Fix crash on launch
Critical fix
v4.0.0 crashed immediately on launch with `ModuleNotFoundError: No module named 'reportlab.graphics.barcode.code128'` — this affected every user, not just the HTML → PDF tool. If you downloaded v4.0.0, please update to this version.
Root cause: the HTML → PDF tool's library (`xhtml2pdf`) pulls in `reportlab.graphics`, which loads some of its submodules dynamically at runtime rather than through plain import statements. The installer's packaging step couldn't see those dynamic imports and left them out, so the app failed to start the moment it tried to register the HTML → PDF page in the sidebar (which happens unconditionally at startup, before you ever touch that tool).
No other changes since v4.0.0.
