- Added stripFireworksDeepSeekThinkingToggle to strip DeepSeek V4 `thinking` metadata before model compatibility is used. - Applied the stripping helper in Fireworks model mapping and generation so produced models exclude the incompatible flag. - Updated completion param construction to remove `thinking` when `reasoning_effort` is sent and added a regression test for Fireworks DeepSeek V4.
