781db9d892 chore: update pyproject.toml files, remove codespell (#33028) 
- Removes Codespell from deps, docs, and `Makefile`s
- Python version requirements in all `pyproject.toml` files now use the
`~=` (compatible release) specifier
- All dependency groups and main dependencies now use explicit lower and
upper bounds, reducing potential for breaking changes

90280d1f58 docs(core): fix bugs and improve example code in chat_history.py (#32994) 
## Summary

This PR fixes several bugs and improves the example code in
`BaseChatMessageHistory` docstring that would prevent it from working
correctly.

### Bugs Fixed
- **Critical bug**: Fixed `json.dump(messages, f)` →
`json.dump(serialized, f)` - was using wrong variable
- **NameError**: Fixed bare variable references to use
`self.storage_path` and `self.session_id`
- **Missing imports**: Added required imports (`json`, `os`, message
converters) to make example runnable

### Improvements
- Added missing type hints following project standards (`messages() ->
list[BaseMessage]`, `clear() -> None`)
- Added robust error handling with `FileNotFoundError` exception
handling
- Added directory creation with `os.makedirs(exist_ok=True)` to prevent
path errors
- Improved performance: `json.load(f)` instead of `json.loads(f.read())`
- Added explicit UTF-8 encoding to all file operations
- Updated stores.py to use modern union syntax (`int | None` vs
`Optional[int]`)

### Test Plan
- [x] Code passes linting (`ruff check`)
- [x] Example code now has all required imports and proper syntax
- [x] Fixed variable references prevent runtime errors
- [x] Follows project's type annotation standards

The example code in the docstring is now fully functional and follows
LangChain's coding standards.

7702691baf core and langchain: Remove upper bound restriction langsmith dependency (#31629) 
Remove upper bound limitation of LS for good measure: we have full
control over LS so we'll be careful when minor bumping so this shouldn't
risk too much, while on the other hand existing such upperboud
restriction will likely introduce occasional dependency headache for
users

Small update just to expand the list of well known tools. This is
necessary while the logic lives in langchain-core.
