feat: initial release of SplitOverlay (KeyOverlay 1.0.0)

Semi-transparent always-on-top Windows overlay that shows the keymap of a Vial/QMK split keyboard (Silakka54). - draws all layers from a Vial .vil layout, transparent keys fall through - detects the active layer from the keyboard via a Raw HID command (firmware/) - shows characters of the active Windows input language - can split the two halves into separate, independently movable windows - highlights pressed keys; tray menu for opacity, size and options - Inno Setup installer and portable build; GitHub-style CI workflow
