breaking changes in the litellm wrapper package.

 ### Changed
 - Added upper-bound version constraints (`<next_major`) to all dependencies to prevent unexpected breaking changes from major-version upgrades.
-- `langchain-litellm` upper-bounded at `<1.0.0`.
+- `langchain-litellm` is pinned to an exact version (`==0.6.4`) alongside `litellm`.
 - Minimum `uipath-llm-client` bumped to 1.9.8 to match the core dependency-constraints release.
