refactor: refactor prompt handling logic and improve code clarity

- Add detailed comments explaining the `promptCmd` command functionality
- Refactor the conditional check for `loadPromptData` to return early if not set
- Replace variable `change` with `confirm` for clarity
- Extract the prompt data saving logic into a new function `savePromptData`
