BlissOS/platform_manifest — reverse-engineered prompt

Help me turn this repo into a repeatable BlissOS build setup for x86 PC on a recent Ubuntu LTS machine. I want a working ISO built from the typhoon x86 branch, starting from a clean system, and I need you to handle the full flow, including the repo init and sync, required system packages, Rust tools, and the Ubuntu 24.04 ncurses compatibility workaround if it is still needed. Use the standard bliss_x86_64 userdebug target and build the ISO with the normal process.

Please make it easy to rebuild later, ideally with a simple script or very clear notes. If this project already supports different build flavors like vanilla, foss, gapps, pixelgapps, or microg, set it up so I can switch those with simple environment variables, but default to vanilla. If special variants for devices like Surface or Steam Deck are already supported here, keep those available too. If anything is unclear or outdated, look up the current docs online and use the safest working approach.
