feat: add reasoning effort support to Chutes provider models

[roomote]

Summary

This PR adds reasoning effort support to the Chutes provider, addressing Issue #8904.

What's Changed

✨ Features Added

• Reasoning Effort Support: Added reasoning effort configuration for 8 Chutes models that support advanced reasoning capabilities
• UI Integration: Integrated the ThinkingBudget component into Chutes provider settings to allow users to configure reasoning effort levels (low, medium, high)
• API Parameter Handling: Updated ChutesHandler to properly pass reasoning_effort parameter to API calls

📋 Models with Reasoning Effort Support

The following models now support reasoning effort configuration:

• deepseek-ai/DeepSeek-R1-0528
• deepseek-ai/DeepSeek-R1
• deepseek-ai/DeepSeek-R1-Zero
• tngtech/DeepSeek-R1T-Chimera
• meituan-longcat/LongCat-Flash-Thinking-FP8
• Qwen/Qwen3-235B-A22B-Thinking-2507
• Qwen/Qwen3-Next-80B-A3B-Thinking
• Qwen/Qwen3-VL-235B-A22B-Thinking

🧪 Testing

• Added comprehensive test coverage with 150+ lines of new tests
• All existing tests continue to pass
• New tests specifically validate reasoning effort parameter handling

📝 Implementation Details

• Used consistent patterns from other providers (Anthropic, OpenAI)
• Leveraged centralized parameter handling via getModelParams
• Applied proper max_tokens calculation using getModelMaxOutputTokens
• Default reasoning effort set to "medium" for all reasoning-capable models

Related Issue

Fixes #8904

Screenshots

The reasoning effort UI now appears in Chutes provider settings similar to other providers:

• Dropdown to select effort level (low, medium, high)
• Only shown for models that support reasoning

Review Notes

The implementation follows established patterns and maintains consistency with existing provider implementations. No breaking changes or security issues were introduced.

Important

Adds reasoning effort support to Chutes models, updates UI for configuration, and ensures API calls handle the new parameter with comprehensive testing.

• Behavior:
  • Adds reasoning effort support to 8 Chutes models in chutes.ts with default "medium" level.
  • Updates ChutesHandler in chutes.ts to pass reasoning_effort parameter in API calls.
  • Integrates ThinkingBudget component in Chutes.tsx for UI configuration of reasoning effort levels.
• Testing:
  • Adds tests in chutes.spec.ts to validate reasoning effort handling for supported and unsupported models.
  • Tests ensure default reasoning effort is used when not explicitly set and verify correct API parameter passing.
• Misc:
  • Uses centralized parameter handling via getModelParams and getModelMaxOutputTokens in chutes.ts.
  • Default reasoning effort set to "medium" for reasoning-capable models.

The changes follow established patterns from other providers and include:

• Proper model configuration with supportsReasoningEffort: true and default reasoningEffort: "medium"
• Integration with centralized parameter handling via getModelParams
• UI integration through the ThinkingBudget component
• Comprehensive test coverage validating all scenarios

The implementation is consistent, well-tested, and ready for merge.
