Help me install and set up CleanYourTV on my Android/Google TV using this GitHub repo: https://github.com/Gathin23/cleanyourtv Read the README and PROMPT.md, then guide me through the setup step by step. Connect to my TV over Wi-Fi using ADB, back up its current settings, remove unnecessary bloatware and ads, and install the clean Apple TV-style launcher. Keep my streaming apps, casting, Wi-Fi, and system updates working. Ask before making changes, and make sure everything can be restored.
Do not install every repo just because it is on this list.
Add new repos when you actually run into a problem they solve.
A smaller Claude setup you understand is more useful than installing dozens of repos you never use.
