chore: Add INFO-level logging for hook_config debugging

[xingyaoww]

Summary

Add INFO-level logging at key points to trace hook_config flow through the system.

Background

When debugging hook deployment issues in OpenHands PR #12773, we found that:

1. ✅ App-server loads hooks from workspace correctly
2. ✅ App-server sends hook_config in StartConversationRequest
3. ❓ Agent-server receives the request but hooks don't execute

Changes

Add logging to trace hook_config at three key points:

1. conversation_service.py

• Log when request is received (shows if hook_config exists in request)
• Log when StoredConversation is created (shows if hook_config was deserialized)

2. event_service.py

• Log when LocalConversation is created with hook_config from stored

3. local_conversation.py

• Log _pending_hook_config during plugin loading
• Log final_hook_config after merging with plugin hooks
• Log hook processor creation success
• Log when stop hooks are checked (on agent FINISHED)
• Log stop hook execution result

Expected Log Output

With these changes, we should see logs like:

Creating StoredConversation - request has hook_config: True, hook_config value: {...}
StoredConversation created - stored.hook_config: HookConfig(...)
Creating LocalConversation with hook_config from stored: HookConfig(...)
LocalConversation created with _pending_hook_config: HookConfig(...)
_ensure_plugins_loaded: _pending_hook_config=HookConfig(...)
_ensure_plugins_loaded: final_hook_config=HookConfig(...)
Hook processor created successfully, has_stop_hooks=True
Agent FINISHED - checking stop hooks. _hook_processor=True
Running stop hooks...
Stop hook result: should_stop=True, feedback=...

Testing

This is a debugging change - the new logging will help identify where hook_config is being lost or why hooks aren't executing.

About Multi-Architecture Support

• Each variant tag (e.g., 407b24d-python) is a multi-arch manifest supporting both amd64 and arm64
• Docker automatically pulls the correct architecture for your platform
• Individual architecture tags (e.g., 407b24d-python-amd64) are also available if needed
