Usage: uninstall.sh [OPTIONS]

Options:
  --cli-only    Remove only the 4 CLI symlinks from ~/.local/bin/.
                Skips plugin and skill removal.

  --help, -h    Show this help and exit.

Modes:
  (no flags)    Remove all symlinks: CLI + plugin + skill.

  --cli-only    Remove only bgrun bgstatus bgtail bgclean from ~/.local/bin/.

Safety: only removes symlinks whose target is under either:
  • This repo directory ($SCRIPT_DIR)
  • The OpenCode plugin cache (~/.cache/opencode/packages/opencode-bgrun*)
Real files and symlinks pointing elsewhere are left untouched.
