engine: 5.8.4 extracted and initialising on Bazzite

Browse Source 
Extraction finished clean (73 GB). The editor crashed twice with signal 11, but
the log named the real cause: the agent shell's home is read-only, so the editor
could not create ~/.config/Epic and died in pre-init. With HOME redirected it
reaches 'Engine is initialized' under -NullRHI, proving the install and bundled
libraries are sound on Bazzite.

The Vulkan RHI is still unproven: the successful run used -NullRHI. A desktop
terminal run is the remaining step, recorded in Docs/environment.md, ROADMAP and
the toolchain pin.

- [x] Update Bazzite using its supported mechanism; verify NVIDIA driver and Vulkan operation.
- [x] Register an Epic account and accept the Unreal license; obtain a pinned Linux engine build or build from Epic's authorized source repository.
- [-] Validate Unreal runs on Bazzite before asset production (not an officially supported distribution). The 5.8.4 archive is verified (37.08 GiB, 299 959 entries, CL 58902052) and extracting to `/run/media/system/DATA/Engines/UE_5.8.4`; the editor has not been launched yet.
- [-] Install the engine-required compiler/SDK, Git, Git LFS, and an editor; use Distrobox for isolated CLI dependencies where useful.
- [-] Pin Blender, MPFB, Blosm, and QGIS versions; confirm add-on compatibility; record in `docs/toolchain.md`. Done: Blender 5.2.0 LTS, MPFB 2.0.18, Blosm 2.7.28 (imports headless on 5.2 in `3Dsimple`; two headless workarounds documented), QGIS 4.2.3 with PROJ 9.9.0. Left: uninstall the stale QGIS `lts` 3.28.9 beside it, and record Unreal's pin once it launches.
- [-] Validate Unreal runs on Bazzite before asset production (not an officially supported distribution). 5.8.4 fully extracted (73 GiB, CL 58902052, promoted build); headless smoke test passed 2026-11-07 (`UnrealEditor-Cmd -nullrhi -run=BlankProgram`, clean startup and shutdown). Editor GUI launch on Vulkan still pending.
- [-] Install the engine-required compiler/SDK, Git, Git LFS, and an editor; use Distrobox for isolated CLI dependencies where useful. clang 23.1.4 / cmake 4.3.0 / ninja 1.13.2 installed; verified 2026-11-07 that this engine build bundles no Linux clang, so the system compiler is the toolchain — final proof lands with the first C++ project compile.
- [-] Pin Blender, MPFB, Blosm, and QGIS versions; confirm add-on compatibility; record in `docs/toolchain.md`. Done: Blender 5.2.0 LTS, MPFB 2.0.18, Blosm 2.7.28 (imports headless on 5.2 in `3Dsimple`; two headless workarounds documented), QGIS 4.2.3 with PROJ 9.9.0, stale QGIS `lts` 3.28.9 uninstalled 2026-11-07, Unreal 5.8.4 recorded as pin in `Docs/toolchain.md`. Left: finalize the Unreal pin once the editor GUI launches.
- [x] Create repository structure (`Game/`, `Art/`, `Geo/`, `Tools/`, `Docs/`) with LFS tracking and ignore rules applied.
- [x] Keep project and Derived Data Cache on SSD storage; reserve several hundred GB for engine, assets, caches, builds.
