This makes sense but needs to resolve discussions.

Was generative AI tooling used to co-author this PR?
Tasks can record per-emission partition keys via outlet_events[asset].add_partitions(...) (shipped in #65447).
Persist each on the matching AssetEvent row, fanning runtime fan-out emissions into one event per key, and back-fill
DagRun.partition_key when the task emitted exactly one key on a run that had none.
