Issue : Groq API Rate Limit Error Handling

[jiveshkalra]

Describe your issue

Currently the Groq client in the src/llm/groq_client.py doesnt have any error handling , while such code might be okay for other APIs which have bigger token limit but Groq Llama3 70b has a rate limit of 6k tokens PER MINUTE, which get reached very easily by devika
and as soon as that limit is reached , error pops up in the devika backend console and the current task gets stopped.

How To Reproduce

Steps to reproduce the behavior (example):

1. Setup Devika with GROQ API
2. Select Llama3 70B as a model
3. Give a big problem that requires longer token limit (tbh any complex task will do)

Expected behavior

If the rate limit is reached for that minute , the agent should take a pause and then resume the task instead of abruptly stopping everything
