Rename the package payload folder to RIOJoy (was riojoy) so it extracts
to C:\games\RIOJoy, and add a pre-uninstall path the console can run
before deleting the folder.
- pre-uninstall.bat (inside RIOJoy\): self-elevating entry point that
runs uninstall-rio.ps1.
- uninstall-rio.ps1: stops the tray app, removes the HKLM Run entry,
uninstalls ViGEmBus (-KeepDriver to skip), and clears per-user config
for every profile (-KeepConfig to skip). Idempotent and non-fatal.
- build-package.ps1 bundles both; README documents the uninstall flow.
