Head commit for run: 8349cb8fa3ae21bcad770bc0dcad922621ab9887 / 1fanwang <[email protected]> feat(metrics): emit dagrun.first_task_start_delay separate from scheduling_delay `dagrun.first_task_scheduling_delay` measures `data_interval_end -> first_start_date`, which conflates scheduler-enqueue latency with executor-pickup latency. When a Dag run's first task starts late, ops can't tell from this single timer whether the scheduler was slow to queue the task or the executor was slow to pick it up. Add `dagrun.first_task_start_delay`, computed as `first_start_date - queued_at`, tagged by `dag_id` and `run_type` to match the existing tag shape. It is emitted next to the existing scheduling-delay metric on Dag run completion, only when `queued_at` is set and the delta is positive.
