docs: bring setup and toolchain in line with a finished bootstrap

Initial setup is complete: setup.md opens with a per-section status table and
drops the stale blockers, toolchain.md records that every pin has been exercised
on real work (engine compile + package, Blender/MPFB/Blosm assets, PROJ origin),
and MPFB's load-and-export check moves from pending to verified. Records the one
unexercised path — a fresh checkout — as a v0.1.0 release check.

+**Initial setup is complete.** Sections 1 to 4 are done and verified; the project builds, packages, and imports Blender assets with the pinned toolchain. What remains in section 3 is one optional geo environment.

+| 5. Repository | procedure documented; a fresh checkout has not yet been exercised end to end |

+- `[ ]` **Optional.** Confirm the geo tool Python environment (venv with `pyproj`, `GDAL`, `shapely`). Not needed so far: every geo script in `Geo/scripts/` is standard-library only, and PROJ 9.9.0 is invoked from the QGIS Flatpak (`LD_LIBRARY_PATH` trick in `Geo/manifests/local-origin.md`). Add the venv only when a step genuinely needs `pyproj` or GDAL in-process.

 Closed 2026-11-07: Epic account and engine download, QGIS `lts` removal, Blosm and MPFB on Blender 5.2 (headless invocation fix in `Art/blender/README.md`), engine validation on Bazzite, full project bootstrap. Earlier closed: Bazzite update and reboot, driver and Vulkan verification, `git-lfs`/`clang`/`cmake`/`ninja` layering.
