Add the [batch] config block (Batch type + File.Batch) and ParseSize (binary KiB/MiB/GiB byte counts) in internal/config. serve now opens the dcache store when batch is on, marks the queued/running jobs a restart killed as failed (never resumed) and observes them, builds the runner from the config with the runner's defaults filling zeros, and closes the runner on both shutdown paths. Batch is on by default; disabled = true leaves srv.Batch nil so the endpoints answer 503. Co-Authored-By: ornith-1.5-35b-a3b <ornith-1.5-35b-a3b@llama.cpp.invalid>
