The hot-sweep variant of B3 writes one shared engine_state across all policies; the isolated variant writes per-policy. Previously slice_engine_state.py was called unconditionally and would overwrite an isolated policy's real data with an empty slice (the isolated policy's run-window doesn't overlap with the shared dir's contents). Now we check the policy directory's engine_state for any non-empty engine_*.jsonl first; if present, use it directly; else slice from the shared one as before.
