Two TaskStore instances writing to the same task concurrently raced on a
shared task.json.tmp filename: one writer's rename consumed the tmp file,
the other ENOENTed. withTaskLock only serializes within a single store
instance, so cross-process writers (engine + dashboard server) were
unprotected.
Each write now uses task.json.<pid>.<uuid>.tmp and cleans up its own tmp
on rename failure. Adds a regression test that drives 40 concurrent
same-task updates across 4 TaskStore instances.
Fixes FN-4122, FN-4123, FN-4148.
