feat(theme): add catppuccin themes with transparency and 256-color support

Add a theme package providing all four catppuccin flavors (mocha, frappe, macchiato, latte) mapped to the xterm-256 palette. Themes are selected with -theme or the CTOP_THEME environment variable; -i inverts the flavor. Background slots use the terminal's native color for transparency (opt out with -solid / CTOP_SOLID), and termbox is switched to Output256 so colors render correctly. Replace hardcoded colors in the compact and single views with ctheme portrait slots.
