Added interaction count tracking for sessions with Redis or in-memory fallback. Implemented conversation history replacement functionality to compact and update message history. The changes include:
- New AtomicUsize counter in SessionManager for interaction tracking
- increment_and_get_interaction_count method with Redis support
- replace_conversation_history to update and compact message history
- Maintains existing functionality while adding new features
Add logic to automatically upload an initial `config.csv` to the default S3 bucket during bootstrap. Enhance S3 operator creation by ensuring endpoint formatting, setting default bucket and region, and enabling path style. Improve template upload flow by validating bucket existence and creating it if missing. Also include debug logging for better traceability.
Eliminates the `s3_bucket` field from `AppConfig` and deletes related initialization code in `main.rs`. This simplifies configuration management since S3 bucket handling is no longer required or used in the application.
