Feature Request: Add Support for More LLM Providers (Anthropic, Gemini, etc.) #1

Description

Currently, transmeet supports only Groq and OpenAI clients for LLM-based tasks like response generation and audio transcription. To make the platform more flexible and future-proof, it would be valuable to support additional LLM providers such as:

• Anthropic Claude
• Google Gemini
• Mistral
• Cohere
• Open-source models via Ollama or Hugging Face

Proposed Enhancement

🔧 Introduce pluggable support for additional providers via:

• Extension of BaseLLMClass
• Factory pattern (LLMFactory) that dynamically resolves based on provider name
• Graceful fallbacks for features not supported (e.g., transcription)
