The two Unix-permission tests called Skip.IfNot from a plain [Fact] (xunit v2 +
Xunit.SkippableFact) so they failed on Windows; now [SkippableFact].
Resolver_Works_EndToEnd_ThroughDi calls SqliteConnection.ClearAllPools() before
deleting its temp DB.

Environment.SetEnvironmentVariable/GetEnvironmentVariable mutate the
process-wide environ; concurrent setenv/getenv across parallel xunit test
classes is a documented crash/flake source on glibc even with unique
variable names. Group the six classes that touch process env vars into a
DisableParallelization=true collection so they run serially against each
other while everything else keeps running in parallel.
