2nd package in this repo: langgraph-checkpoint-mongodb

Implements two new graph checkpointers for MongoDB. One synchronous and one asynchronous.
This closely follows the other implementations in checkpoint, checkpoint-postgres, checkpoint-sqlite but with NoSQL idioms.

This is work that was originally in a pull-request directly to langgraph (#2089)

In the review of #2089, we were told that there were additional tests that truly verified the checkpointers, this file for sync and this file for async. This PR will be marled draft until these are all green.

Looks good to me! for final version we'd need to remove the pregel test files. will let you know once standard test lib is ready :)

Discussed offline -- we can merge as is and rip those tests out as soon as standard tests lib is published
