# Daemora installer for Windows — one-shot setup for non-technical users.
#
# What this does, in order:
#   1. Detects Node.js; installs 22 LTS via winget if missing or too old.
#   2. Installs the `daemora` npm package globally so the `daemora`
#      command is on PATH.
#   3. Drops a small launcher .bat at %USERPROFILE%\.daemora\bin\ that
#      starts the agent and waits for the HTTP port before opening the
#      browser.
#   4. Creates Desktop + Start Menu shortcuts pointing at the launcher.
#   5. Launches Daemora so the dashboard opens immediately on first
#      install.
#
# First run: the launcher hits `daemora start`, which runs the existing
# setup wizard if config isn't done. Subsequent runs: the launcher just
# opens the browser if the agent is already running, or restarts it.
#
# Usage (PowerShell, run as user — winget will UAC-prompt if Node needs
# installing):
