ToyLoRA / ToyControlNet / ToyTargetModel / ToyDraftModel / ToyRewardModel (+ the
_spec_target_next helper) in the toy backend, and build_karras_sigmas in the
sampler, were defined but referenced nowhere — no recipe, card, loop, test, or
example used them. They were toy stand-ins for capabilities (adapter plane,
speculative decode, served reward) and an EDM/Karras noise schedule that were
written ahead of being wired. Remove them (-134 LOC); a toy can be re-added when
the capability is actually wired. No thesis impact, no behavior change.
Suite green: 143 passed, 2 skipped (toy backend); import v2 stays torch-free.
