Added a color scheme / font switcher thingie.

• Add 6 built-in color themes: Catppuccin Mocha (default), Nord, Dracula, Solarized Dark, Monokai, Light — configurable via preferences { theme = "name" }.
• Add font size picker with preset buttons (10–24 px) and config support via preferences { font_size = N }.
• Add font family picker with 8 monospace fonts and in-font preview, configurable via preferences { font_family = "...' }.
• Add color palette overrides via preferences { color_palette_overrides = [...] }.
• Add cursor style (block/underline/bar), cursor blink, and scrollback lines to preferences.
• Add Display Customization section to README documenting all new features.
