New -cores N / -memory M (MiB) flags for --selftest=bring-up|provision (0 = keep golden default), flowed through bringUpSizing into reconcile.BringUpSpec so the existing buildBringUpConfig emits cores/memory into the pre-start config PUT (the cap lands before first boot). No engine change. New pure-function test TestBuildBringUpConfig_ResourceCaps asserts the set + omit-when-zero cases (red-proof run + reverted). go build/vet/test clean.
