#!/usr/bin/env bash
# install.sh — Build Pushling, install to /Applications, set up LaunchAgent
#
# Usage:
#   ./install.sh            # Build release, install, set up LaunchAgent
#   ./install.sh --uninstall  # Remove from /Applications and unload LaunchAgent
#
# This installs Pushling as a login item that starts automatically.
# The app runs as a menu-bar daemon (no dock icon, no windows).
