Description
In run_agent.py line 5522, _build_api_kwargs() calls:

fast_mode=self.request_overrides.get("speed") == "fast",

This crashes with 'NoneType' object has no attribute 'get' when self.request_overrides is None.

Root Cause
Although __init__ initializes self.request_overrides = dict(request_overrides or {}), certain code paths may set it to None, leaving the .get() call unprotected.

Fix
Change line 5522 from:

fast_mode=self.request_overrides.get("speed") == "fast",

to:

fast_mode=(self.request_overrides or {}).get("speed") == "fast",

Affected Version
v0.8.0
