Subject: chore: simplify project to engine docs and tests

Remove planning and acceptance scaffolding while retaining the native Vulkan mission preview, format readers, runtime algorithms, and ordinary Rust tests. Keep the book aligned with the runnable project and validate checked-in shaders without generated tool metadata.
