graph激活失败的日志缺少 graph name相关描述

https://github.com/baidu/babylon/blob/571cfb36eaa51eb1b6f1d5b63c515011f979f1bc/src/babylon/anyflow/graph.cpp#L30

如题， graph激活失败的日志缺少 graph name相关描述，导致在有多个图并行跑的场景，不太容易看出是哪个图激活失败了

Open src/babylon/anyflow/graph.cpp at line 30 and inspect the log emitted when graph activation fails. Confirm how the graph name is available at that point, then update the failure log so parallel graph runs identify the failing graph. Verify the resulting log output for multiple graph activations.
