# remote-agent-stack uninstaller
#
# Removes the userland artifacts installed by install.sh:
#   - /usr/local/bin/copilot-agent symlink
#   - /usr/local/bin/ca symlink (short alias)
#   - /usr/local/bin/ss and /usr/local/bin/vncfix symlinks (GUI helpers)
#   - /etc/resolver/ts.net
#   - ~/.tmux.conf managed block (status-bar-off settings)
#
# Does NOT uninstall Homebrew packages (tmux, tailscale) — those may be
# used by other tools on your system. Run `brew uninstall tmux tailscale`
# manually if you want them gone.
#
# Does NOT remove ~/.config/remote-agent-stack/ unless --purge is given.
