uninstall.ps1

# PowerShell uninstall script for copilot_here.
# Self-contained: removes the install by known paths and does NOT depend on the
# binary still working, so it cleans up even a half-broken install.
#
# Usage:
#   iex ([System.Text.Encoding]::UTF8.GetString((iwr -UseBasicParsing 'https://github.com/GordonBeeming/copilot_here/releases/download/cli-latest/uninstall.ps1').Content))
#   Add -Purge to also delete config dirs, -Yes to skip the confirmation prompt:
#   & ([scriptblock]::Create((iwr -UseBasicParsing '.../uninstall.ps1').Content)) -Purge -Yes
