Subject: [PATCH] feat: add Milkdown as default WYSIWYG editor with EasyMDE
 fallback

- Add Milkdown as the default rich editor engine (true WYSIWYG)
- Keep EasyMDE as an alternative option for users who prefer it
- Add "Rich Editor Engine" submenu in Settings to switch between editors
- Pre-bundle Milkdown with esbuild for reliable dependency resolution
- Add Milkdown-specific styles that match the app's dark/light theme
- Editor engine preference is saved to config and restored on launch

Milkdown provides a true WYSIWYG experience where formatting is rendered
inline (bold text appears bold, etc.), while EasyMDE shows markdown syntax
with styling hints. Users can switch between them via Settings menu.
