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.

+# Оригинальные модули
+
+RVA в книге относится к определённой сборке DLL. SHA-256 позволяет
+проверить, что сравнивается тот же код.
+
+## Совпадающие модули частей 1 и 2
+
+| Binary | SHA-256 | Size | Notes |
+| --- | --- | ---: | --- |
+| `Ngi32.dll` | `bab9840d94f4e4e74ffc26677724fa896cf4823845504d09a9e025f80016edf5` | 253952 | Shared low-level render/resource/audio boundary |

+
+## Сборка GOG
+
+The canonical disassembly source is the windowed GOG installation, not the
+Part 1/Part 2 test installations. Its `Terrain.dll` is a distinct revision:
