Sydney Runkle ee5b3c2639 refactor(postgres): replace recursive CTE with two-query ancestor walk for DeltaChannel ...

Instead of a recursive SQL CTE, collect the ancestor checkpoint ID chain in
Python by fetching all (checkpoint_id, parent_checkpoint_id) for the thread
in one query, then fetch writes with a plain WHERE checkpoint_id = ANY(...).

Simpler, avoids recursive query planner overhead, and uses well-indexed lookups.
