Hyprland-Simple-Setup bootstrap installer (curl | bash friendly)

Usage:
  curl -fsSL <raw-install.sh-url> | bash
  curl -fsSL <raw-install.sh-url> | bash -s -- [bootstrap options] -- [setup.sh options]

Bootstrap options:
  --repo <url>     Git repo URL (default: https://github.com/firstp1ck/Hyprland-Simple-Setup.git)
  --ref <ref>      Git ref to checkout (branch/tag/commit). Default: main
  --dir <path>     Install/clone directory (default: $HOME/Hyprland-Simple-Setup)
  --update         If dir exists and is a git repo, pull updates (default: enabled)
  --no-update      Do not pull updates when dir exists
  --tui            Prefer the Rust TUI (default)
  --no-tui         Do not run the TUI; run setup.sh directly
  --dry-run        Convenience: passes --dry-run to setup.sh
  --verbose        Convenience: passes --verbose to setup.sh
  -h, --help       Show this help

Notes:
  - Any args after `--` are passed directly to setup.sh.
  - For unattended runs, you can set env vars used by setup.sh, e.g.:
      NON_INTERACTIVE=true PROMPT_DEFAULT_YN=true BROWSER_CHOICE_OVERRIDE=1 FISH_LANGUAGE_CHOICE_OVERRIDE=1
