Switch to Rose Pine theme and simplify terminal setup

- Switch from Catppuccin to Rose Pine theme across Alacritty, tmux, and btop
- Simplify Starship prompt to minimal (user/folder/git/time moved to tmux)
- Customize tmux status bar: git branch, CPU, battery (no emoji)
- Add git tree alias for pretty log visualization
- Add auto-start tmux in Alacritty (not in SSH sessions)
- Make install.sh executable
- Add THEME_SWITCHING.md documentation
