kindling recipes: control paths are FILES, not the cache dirs — VLLM_{ADAPTIVE_K,DRAFT_TRUNC}_CONTROL pointed at the mounted dir roots, and their _read_control() does os.stat+open on the path (stat succeeds on a dir, open does not) => IsADirectoryError killed the engine core right after KV allocation; point them at <dir>/control (absent file = safe defaults: tau 0.3 / adapt, written file persists + live-control)
