Remove Checkpoint.writes
...
- This has been superseded by saving the individual writes of each task through put_writes()
- Removing this speeds up checkpoint operations as it was duplicating data saved elsewhere already

Remove Checkpoint.pending_sends
...
- Instead store sends in a Topic channel, removing the need to fetch sends as writes against the parent checkpoint
- Remove deprecated/unused functions in langgraph-checkpoint (will require bumping min range for langgraph-checkpoint in langgraph lib)
- Implement migration of old pending sends in langgraph-checkpoint-postgres
- Ensure parent config of `checkpoint_during=False` checkpoints always points to checkpoints that were also saved

ci: migrate to uv! ( #4698 )
...
* Migrate to `uv`
* Format `pyproject.toml` files properly
* Remove upper bounds on dependencies, and bounds on dev dependencies
(we should be using latest)
* Move to hatch for packaing
In the future we should:
* Set up dependabot / automate lockfile updates and tests
* Add tests for min compatible versions (I'll do this right after merge)
* Use dynamic versioning
* Bump `pydantic` to v2.11.4 in the lockfile, we have some tests failing

Fix AsyncPostgresStore._cursor row type ( #4623 )
...
`AsyncPostgresStore._cursor` is expected to yield
`AsyncCursor[DictRow]`. In the `else` branch the `row_factory` was not
defined, meaning that it would yield `AsyncCursor[TupleRow]` (default).
This resulted in an error in
[langgraph/store/postgres/aio.py#L249](https://github.com/langchain-ai/langgraph/blob/main/libs/checkpoint-postgres/langgraph/store/postgres/aio.py#L249 )
(`TypeError: tuple indices must be integers or slices, not str`).

Fix text fields naming ( #4345 )
...
The configuration expects the key "fields", not "text_fields": I had
failed to update across all implementations in the original PR
Thank you to Vincent Min for the fix!
