Updates the minimum Pillow version to address CVE-2026-25990 (HIGH
severity out-of-bounds write vulnerability affecting versions 10.3.0
through 12.1.0).
Changes:
langchain-nomic: pillow>=10.3.0,<13.0.0 → pillow>=12.1.1,<13.0.0
langchain-openai: pillow>=10.3.0,<13.0.0 → pillow>=12.1.1,<13.0.0
langchain-perplexity: pillow>=10.3.0,<13.0.0 → pillow>=12.1.1,<13.0.0
Safety: This is a minimum version bump within the existing constraint
range (<13.0.0), so no breaking changes are introduced.

- 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
Follow up to https://github.com/langchain-ai/langsmith-sdk/pull/1696,
I've bumped the `langsmith` version where applicable in `uv.lock`.
Type checking problems here because deps have been updated in
`pyproject.toml` and `uv lock` hasn't been run - we should enforce that
in the future - goes with the other dependabot todos :).
Perplexity's importance in the space has been growing, so we think it's
time to add an official integration!
Note: following the release of `langchain-perplexity` to `pypi`, we
should be able to add `perplexity` as an extra in
`libs/langchain/pyproject.toml`, but we're blocked by a circular import
for now.
