Feat/deepseek v3.1 thinking support

[shameez-struggles-to-commit]

🎯 Problem

DeepSeek V3.1 models from Chutes.ai were using incorrect chat templates, preventing thinking mode from working properly. The models were being treated as standard OpenAI models instead of using the specialized DeepSeek V3.1 format.

🔧 Solution

• Created specialized chat template for DeepSeek V3.1 models with proper <｜begin▁of▁sentence｜>, <｜User｜>, <｜Assistant｜> format
• Enhanced Chutes.ai provider to detect and route V3.1 models to the correct template
• Updated OpenAI provider with V3.1 model detection logic
• Added model configurations for deepseek-v3.1 and deepseek-v3.1-reasoner with proper pricing

📁 Files Changed

• src/api/transform/deepseek-v3.1-format.ts - New chat template converter
• src/api/providers/chutes.ts - Enhanced with V3.1 support
• src/api/providers/openai.ts - Added V3.1 detection logic
• packages/types/src/providers/deepseek.ts - Added V3.1 model configs

✅ Testing

• ✅ Build completed successfully (51.404s, no errors)
• ✅ All lint and type checks passed
• ✅ Template verified to produce correct format with <think> tags
• ✅ Thinking mode now works properly with V3.1 models

🚀 Impact

Fixes thinking mode for DeepSeek V3.1 models from Chutes.ai, enabling proper reasoning capabilities that were previously broken due to incorrect chat templates.
