AetheriaOS/aetheria_manifest ? reverse-engineered prompt

Help me build the manifest for AetheriaOS so I can sync the right project files for a custom Android style operating system.

I want it to point to the correct repositories and default branch, and keep the setup clean so someone can use it to start a build right away. If there are any missing links or current best practices for manifest files, please look those up and make sure this is set up properly.

Keep it simple and organized, and make sure the default config works out of the box for a fresh checkout.
