refactor: rename states for clarity and consistency

- Updated state names in constants and related files from WAIT, REACT, TYPE, SLEEP to WAITING, REACTING, TYPING, SLEEPING.
- Adjusted all references to the renamed states across the codebase, including state handlers and transition logic.
- Ensured that logging messages reflect the new state names for better readability.
