All dumpbin export/import diffs of grass_gis.8.6.dll's dependency
chain (proj_9.dll, curl, sqlite3, tiff.dll/jpeg62.dll) came back
clean: no removed exports, no broken ordinals, all import hints match
the current builds. Downgrading the MSYS2 mingw-w64 toolchain snapshot
didn't fix the crash either. So no single missing/renamed symbol
explains:
Windows fatal exception: code 0xc0000139
seen loading grass_gis.8.6.dll under pytest-xdist.
This adds a step that imports grass.pygrass.utils (which triggers the
same grass_gis.8.6.dll load) in a single, fresh Python process right
after the grass86.bat smoke tests, before pytest/xdist start. If this
also crashes, the failure is tied to grass_gis.8.6.dll's load in
isolation. If it succeeds, the crash is specific to how pytest-xdist
accumulates loaded DLLs across a worker process (e.g. a Windows/MinGW
TLS-slot exhaustion, since libgomp and other mingw-w64 runtime DLLs
use TLS), not a single missing symbol.
Temporary, for CI investigation only.

Purpose
Fourth diagnostic in this investigation. Every dumpbin export/import
diff of grass_gis.8.6.dll's dependency chain (proj_9.dll's 5 geodesic
functions match hint-for-hint; PROJ's own imports from curl/sqlite3;
tiff.dll's imports from jpeg62.dll by ordinal) came back completely
clean -- see the sibling diagnostic PRs. Downgrading the MSYS2
mingw-w64 toolchain snapshot didn't fix the crash either. So no single
missing/renamed symbol explains:
(STATUS_ENTRYPOINT_NOT_FOUND) seen loading grass_gis.8.6.dll under
pytest-xdist.
