- Set visible process/menu name to 'Prole Installer' via Foundation on macOS.
- Prefer .icns from built Prole.app for Dock icon; fallback to PNG from properties via AppKit.
- Keep Tk iconphoto as a universal fallback.
- Move image configuration to prole-app/prole.properties with new keys:
- icon=img/proleIcon.png
- background=img/proleLogoSepia.png
- Support legacy keys ui.icon and ui.background for backward compatibility.
Files:
- install.py: strengthen _set_app_identity for process title and Dock icon.
- installer/config.py: add getters prioritizing new keys (with fallbacks).
- prole-app/prole.properties: add canonical keys; retain legacy; document.
Result: On macOS the menu bar now shows 'Prole Installer' instead of 'Python' and the Dock uses the Prole 'P' icon by default. Non-macOS behavior unchanged.
