[Bug]: `AttributeError: 'NoneType' object has no attribute 'get'` after fast mode commit

[zhangxiao918]

Bug Description

After upgrading Hermes, Telegram messages trigger retries and eventually fail. Log shows:

File "/home/bluestome/.hermes/hermes-agent/run_agent.py", line 5522, in _build_api_kwargs
    fast_mode=self.request_overrides.get("speed") == "fast",
AttributeError: 'NoneType' object has no attribute 'get'

Steps to Reproduce

1. Upgrade Hermes to a version containing commit 970192f1
2. Send a message via Telegram
3. Observe retry attempts in logs, followed by failure

Expected Behavior

Telegram messages should be processed normally without errors.

Actual Behavior

API call failed after 3 retries. 'NoneType' object has no attribute 'get'
...
File "/home/bluestome/.hermes/hermes-agent/run_agent.py", line 5522, in _build_api_kwargs
    fast_mode=self.request_overrides.get("speed") == "fast",
AttributeError: 'NoneType' object has no attribute 'get'

Relevant Logs / Traceback

Root Cause Analysis (optional)

Commit 970192f1 (feat(gateway): add fast mode support to gateway chats) introduced self.request_overrides.get("speed") at line 5522 in run_agent.py. However, self.request_overrides is None in some code paths, even though __init__ sets self.request_overrides = dict(request_overrides or {}).

Proposed Fix (optional)

# run_agent.py line 5522
fast_mode=(self.request_overrides or {}).get("speed") == "fast",
