fix(llm): load system-prompt from config.csv correctly

- Move system_prompt retrieval inside spawn_blocking closure
- Include system_prompt in the return tuple to fix scope issue
- Add trace logging for debugging system-prompt loading
- GLM-5 and other LLM providers now correctly receive custom system prompts
