- strip old job cache path (constructing an input hash based on all inputs); the cache key based on preprocessed source is now the One True Job Cache
- strip parallelfor-based job submission path (gamethread-blocking); the task path has been enabled for a long while now without issues
- remove the "compile job inputs" debug dump; this is no longer relevant since it's based on inputs to the now-stripped compile job path (similar functionality will be provided by the new form of debug usf once completed)
