- ClusterParallelism now defaults to recommended profile (1 for small VMs)
- Jobs and DumpJobs now use profile values instead of raw CPU counts
- Small VMs (4 cores, 32GB) will now get 'conservative' or 'balanced' profile
  with lower parallelism to avoid 'out of shared memory' errors

This fixes the issue where small VMs defaulted to ClusterParallelism=2
regardless of detected resources, causing restore failures on large DBs.
