feat(settings): add preferred terminal selection

Allow users to choose their preferred terminal app for opening
provider terminals. Supports platform-specific options:
- macOS: Terminal.app, iTerm2, Alacritty, Kitty, Ghostty
- Windows: cmd, PowerShell, Windows Terminal
- Linux: GNOME Terminal, Konsole, Xfce4, Alacritty, Kitty, Ghostty

Falls back to system default if selected terminal is unavailable.
