- Add custom_partition_mapper.py and custom_partition_timetable.py example plugins showing how to ship a custom PartitionMapper and a partitioned Timetable via AirflowPlugin. - Wire all three partition plugin examples (mapper, window, timetable) into the asset-partition docs. - Document FanOutMapper + max_downstream_keys, Window direction (FORWARD/BACKWARD), wait policies (WaitForAll/MinimumCount), and the partitioned vs partitioned_at_runtime distinction.
Rewrite the partitioning section so the two approaches read as kinds of one concept — predetermined (the key is worked out before the run) and runtime (the task records it), and are mutually exclusive — with the section header naming them rather than labelling them generically. Align the custom timetable plugin docstring, and fix prose "DAG" to "Dag" in the @asset section.
