t4ce/TRUEOS ? reverse-engineered prompt

Build me a tiny bootable Rust operating system for modern Intel x86 64 machines, with a clean splash screen, a working bootable ISO, and a simple runtime that can actually do real things on bare metal.

I want it to boot in QEMU and on real hardware, show basic graphics, and try native Intel Gen12 style 3D rendering if the GPU is available. It should also have some simple media or image playback experiments, support async and parallel workloads, and make it easy to extend the system at runtime with blueprints or similar user level add ons.

Please keep the build and release flow working too, including packaging the ISO, checksums, and signed release artifacts, and make sure there’s a clear way to verify a release came from the right source. If anything needs current docs or tooling details, look them up online and use the latest stable approach that fits this project.
