feat: simple COHERE_BASE_URL support using environment variable

Browse source 
Replace enum with dynamic getter to enable runtime environment variable lookup.
CohereConstants.API_URL now automatically uses COHERE_BASE_URL if set,
otherwise defaults to https://api.cohere.ai/v1.

This enables using custom Cohere endpoints (like LiteLLM proxy) for web search
reranking by simply setting the COHERE_BASE_URL environment variable.

Usage:
export COHERE_BASE_URL=http://litellm:8000/v1
export COHERE_API_KEY=your_api_key

The change is backwards compatible and requires no configuration changes.
