* fix: create a symlink on non-elevated windows in docs test
Windows terminals without Developer Mode or elevation cannot create file
symlinks, so the versions publishing integration test failed with EPERM
before it could reach the non-ordinary-file rejection. Fall back to a
directory junction, which is creatable without elevation and hits the
same rejection path.
* fix: detect docs snapshot reparse points with lstat
Classify entries with lstat instead of the readdir dirent so symlinks and
Windows junctions are rejected regardless of how a runtime classifies
them. This keeps the versions integration test's non-ordinary-file
assertion meaningful on non-elevated Windows, where the fixture can only
create a directory junction.
Windows CI runs these documentation contract fixtures under variable load. A degraded runner pushed the preview and versions snapshot integration tests past their 30s ceiling, while a healthy run finishes in seconds. Keep 30s elsewhere and give Windows a 120s ceiling.
