promptext-uninstall-robust.ps1: A safer “download then run” wrapper that fetches the upstream scripts/install.ps1 and runs it with -Uninstall, avoiding irm ... | iex.

Promptext-Uninstall.ps1

# Filename: Promptext-Uninstall.ps1
<#
.SYNOPSIS
Robust uninstaller for the promptext CLI on Windows (PowerShell) using a download-then-run workflow.

.DESCRIPTION
This script uninstalls the promptext CLI by downloading the official installer script from the
promptext GitHub repository (via raw.githubusercontent.com) into a temporary file, then executing it
with the -Uninstall switch.

Why this exists:
- Avoids piping remote content directly into iex ("irm ... | iex -Uninstall").
- Makes the action auditable and easier to troubleshoot.
- Keeps behavior consistent with whatever the upstream project defines as “uninstall”.

The upstream installer/uninstaller typically:
- Removes the install directory (default: %LOCALAPPDATA%\promptext)
- Removes PATH entry (User scope)
- Removes the 'prx' alias line from the PowerShell profile (CurrentUserCurrentHost)

.PARAMETER Branch
Git branch name to fetch the installer from (default: "main").
Change this to "master" if the repo uses that as the default branch.

.EXAMPLE
# Uninstall using the default branch ("main") upstream script
powershell -ExecutionPolicy Bypass -File .\promptext-uninstall-robust.ps1

.EXAMPLE
# Uninstall using a different branch (e.g., master)
powershell -ExecutionPolicy Bypass -File .\promptext-uninstall-robust.ps1 -Branch master

.NOTES
v1.0
- Robust "download then execute" wrapper around the upstream uninstaller behavior:
  https://raw.githubusercontent.com/1broseidon/promptext/<branch>/scripts/install.ps1 -Uninstall

Security note:
- Always review scripts before running them in sensitive environments.
