Description
Summary:
Following #1176 and with the addition of Pathfinder, a lot of the primary usages of cmdstan models are able to use threading, but only if STAN_THREADS is True.
I believe this has some downsides for single threaded performance (though I have never seen hard numbers), but it may be worth discussing moving this from an opt-in to an opt-out
Current Version:
v2.32.2

Research direction
No files or tests are named. Start by reviewing issue #1176 and the Pathfinder-related CmdStan model usage described here, then compare single-threaded performance with STAN_THREADS enabled and disabled. Done means establishing whether the default should change and identifying the configuration paths and tests that require updates.
