Add UIAutomation background injection for Roblox Studio

- bg_inject.ps1: PowerShell UIAutomation script that finds Studio command bar by AutomationId and injects Lua code without window focus
- bg_inject.py: Python wrapper for bg_inject.ps1
- bg_inject_uia2.ps1: Discovery/debugging script for finding Studio UI controls
- inject_full_gta.py: 7-step GTA city + COD weapons + enemies injection using background API
- inject_gta_bg.py: Alternative multi-file GTA injection loader
