feat(automation): improve prompt handling and message processing

- Add initial instruction to compact_prompt_for_bots summary request
- Store processed content separately before formatting as summary
- Save filtered content instead of formatted summary in session manager
- Remove max_tokens limit from OpenAI client request
- Refactor message parsing logic to avoid empty content messages
- Improve role-based message handling in OpenAIClient
