process.New applies its options and discards the error they return. When
WithTemporaryStateDir could not create a directory, StateDir stayed
empty and every later option went unapplied, so the failure surfaced
from Run as "mkdir : no such file or directory" naming no path.
That message cost a full day of diagnosis on a worker whose volume was
full: the real errno was ENOSPC and nothing reported it.
The loader now creates the directory itself and returns the underlying
error with the path attached.
