Fix Together AI 404 errors caused by inconsistent fingerprint generation

[Copilot]

Together AI requests fail with 404 after 2-3 messages because each fingerprint generation creates a new LitAgent instance with a different random IP pool, triggering anti-bot measures.

Changes

Root cause: Static generate_fingerprint() method instantiates new LitAgent on every call, causing IPs to jump between unrelated pools:

# Before: Each call gets IP from a NEW random pool
@staticmethod
def generate_fingerprint(browser):
    agent = LitAgent()  # Fresh instance = fresh IP pool
    return {"x-forwarded-for": agent.rotate_ip(), ...}

Fix: Instance-based fingerprint generation using shared LitAgent:

# After: IPs rotate within SAME pool throughout session
def __init__(self):
    self._agent = LitAgent()  # Single instance per provider

def _generate_consistent_fingerprint(self, browser):
    return {"x-forwarded-for": self._agent.rotate_ip(), ...}

Modified files

• Provider/TogetherAI.py: Added _generate_consistent_fingerprint() instance method, updated refresh_identity() to maintain IP header consistency
• Provider/TTI/together.py: Cache fingerprint per session in build_headers(), added _generate_consistent_fingerprint() to Images class
• Provider/OPENAI/TogetherAI.py: Replaced static fingerprint call with instance method

All implementations include defensive hasattr() check for random_id method.

Result

IPs now rotate predictably (e.g., 192.168.1.1 → 192.168.1.2 → 192.168.1.3) instead of randomly jumping pools, eliminating 404s while maintaining anti-fingerprinting rotation.

<issue_description>Hey there!

Hope you're doing great. Thanks for the project.

Quick question, I am trying to use the together ai provider with the lit agent implementation you did. But when making the request after two or three times on the same chat conversation I get '404 error code ' not found'

I have tried many times but the last time I needed to close the tab I was on the chat and then start again and sometimes even after that stop working.

Could you please double check the code and verify is the issue is normal or should i do further implementation.

Thanks.</issue_description>
