:herb: Fern Regeneration -- April 15, 2026 (#156)

* SDK regeneration

* Implement range filter expansion for video parameters in VideosClientWrapper and AsyncVideosClientWrapper. Update duration, fps, width, height, and size parameters to support both exact and range filtering using dictionaries. Enhance documentation to reflect these changes.

* Fix mypy LSP violation by including parent class types in wrapper parameter unions

The VideosClientWrapper and AsyncVideosClientWrapper list() methods override
parent class parameters with incompatible types. Include the original Pydantic
model types (VideosListRequestDuration, etc.) in the Union to satisfy LSP.
