Updated references from `redis_client`, `s3_client`, and `custom_conn` to unified names `cache`, `drive`, and `conn` for consistency across modules. Adjusted `add_suggestion_keyword` to use clearer parameter naming and enhanced custom syntax registration for better readability and maintainability.
Changed the Redis RPUSH command to return the new list length (`Result<i64, RedisError>`) and added a debug log that includes this length. Updated the HSET command to capture its result (`Result<i64, RedisError>`), logging the number of fields added on success and handling errors explicitly. Removed unnecessary `unwrap_or_else` and added comments to clarify behavior, improving observability and error handling for suggestion storage.
Added new `add_suggestion` module to support suggestion handling logic.
Updated `index.html` to include a dynamic suggestions container that fetches and displays context suggestions.
This improves user experience by enabling quick context changes through interactive suggestion buttons.
