# uninstall.ps1 — stop and remove Manage Server containers on Windows.
#
# By default, KEEPS the PostgreSQL volume (scan history, hosts, users)
# and the installer directory (preserves .env secrets for reinstall).
# Pass -PurgeData to delete volumes + installer directory — irreversible.
#
# Usage:
#   .\uninstall.ps1              # stop + remove containers, keep DB + .env
#   .\uninstall.ps1 -PurgeData   # also delete DB, volumes, and installer dir
