This auto generates partner migrations.
At the moment the migration is from community -> partner.
So one would need to run the migration script twice to go from langchain to partner.
Add script to help generate migrations.
This works well for partner packages. Migrations are generated based on run time rather than static analysis (much simpler to get the correct migrations implemented).
The script for generating migrations from langchain to community still needs work.
Will run all CI because of _test change, but future PRs against CLI will
only trigger the new CLI one
Has a bunch of file changes related to formatting/linting.
No mypy yet - coming soon
