feat(models): add doubao_after_251015 reasoning model type and support (#10826)

* feat(models): add doubao_after_251015 model type and support

Add new model type 'doubao_after_251015' with reasoning effort levels and update regex patterns to handle version 251015 and later

* fix(sdk): add warning for reasoning_effort field and update reasoning logic

Add warning comment about reasoning_effort field being overwritten for openai-compatible providers
Update reasoning effort logic to handle Doubao seed models after 251015 and standardize field naming

* fix(reasoning): update Doubao model regex patterns and tests

Update regex patterns for Doubao model validation to correctly handle version constraints
Add comprehensive test cases for model validation functions

(cherry picked from commit 06b1ae0cb8)
