- Remove double str() normalization in _resolve_channel_prompt since
config bridging already handles numeric YAML key conversion
- Remove dead prompts.get(str(key)) fallback that could never match
after keys were already normalized to strings
- Replace getattr(event, "channel_prompt", None) with direct attribute
access since channel_prompt is a declared dataclass field
- Update test to verify normalization responsibility lives in config bridging
