Add CometAPI Support with Comprehensive Model Integration

Description

This PR introduces complete support for CometAPI. #3133

Key Features Added:

• 🚀 CometAPIModel Class: Full OpenAI-compatible model implementation with chat completion and streaming support
• 🔧 CometAPIConfig: Comprehensive configuration class for API key management and model parameters
• 🎯 30 Model Types: Complete support for all CometAPI model series with proper token limits (128K for all models)
• 🏭 Factory Integration: Seamless integration with CAMEL's ModelFactory pattern
• 🔍 Type System: Added is_cometapi property and unified model type detection
• 📚 Documentation: Complete usage examples, API docs, and integration guides
• ✅ Testing: 33 comprehensive tests with 100% code coverage
• 🔄 CI/CD: Updated GitHub Actions workflows for proper testing

Technical Implementation:

1. Model Architecture: Extends OpenAICompatibleModel base class for maximum compatibility
2. Authentication: Bearer token authentication with COMETAPI_KEY environment variable
3. API Endpoint: Uses https://api.cometapi.com/v1/ with OpenAI-compatible format
4. Error Handling: Robust error handling and validation for API calls
5. Streaming Support: Full streaming response capability for real-time interactions

Models Supported:

• GPT Series (9 models): GPT-5, GPT-4.1, ChatGPT-4o, O3/O4 variants
• Claude Series (6 models): Claude Opus 4.1, Sonnet 4, 3.7 Sonnet, 3.5 Haiku (including thinking variants)
• Gemini Series (4 models): Gemini 2.5 Pro/Flash variants, Gemini 2.0 Flash
• Grok Series (4 models): Grok-4, Grok-3, Grok-2 Image variants
• DeepSeek Series (5 models): DeepSeek V3.1, R1, Reasoner, Chat variants
• Qwen Series (2 models): Qwen3 30B A3B, Qwen3 Coder Plus

Usage Example:

from camel.models import ModelFactory
from camel.types import ModelPlatformType, ModelType
from camel.configs import CometAPIConfig

# Create CometAPI model
model = ModelFactory.create(
    api_key="YOUR_COMETAPI_KEY",  # Your CometAPI key here
    model_platform=ModelPlatformType.COMETAPI,
    model_type=ModelType.COMETAPI_GPT_5_CHAT_LATEST,
    model_config_dict=CometAPIConfig(temperature=0.2).as_dict(),
)

# Use with ChatAgent
from camel.agents import ChatAgent
agent = ChatAgent(system_message="You are a helpful assistant.", model=model)
response = agent.step("Hello, CometAPI!")

Testing Results:

• ✅ 33 tests passed with 100% code coverage
• ✅ Real API testing conducted with actual CometAPI key
• ✅ Multiple model validation across different series
• ✅ Configuration testing with custom parameters
• ✅ Error handling validation for edge cases

Performance & Quality:

• Code Quality: Follows CAMEL coding standards with proper logging, type hints, and docstrings
• Error Handling: Comprehensive error handling for API failures and invalid configurations
• Memory Efficiency: Efficient resource management and proper cleanup
• Thread Safety: Safe for concurrent usage in multi-agent scenarios
• Backwards Compatibility: No breaking changes to existing functionality

Real-World Testing:

This integration has been thoroughly tested with actual CometAPI credentials, confirming:
