Description

This pull request modifies the AddIntention.tsx file, which is responsible for rendering the component that allows users to add new intentions to the system. The changes made in this file aim to enhance the user experience by improving the input validation and error handling mechanisms.

Specifically, the following updates have been implemented:

1. Input Validation: The input field for entering the intention now enforces stricter validation rules. Users will be prompted with appropriate error messages if they attempt to submit an empty intention or if the intention exceeds the maximum allowed length.

2. Error Handling: The error handling mechanism has been improved to provide more informative and user-friendly error messages. In case of any API or server-side errors, users will now see clear and concise messages explaining the issue, rather than generic error messages.

3. Accessibility Improvements: Minor accessibility enhancements have been made to ensure better compliance with WCAG guidelines. This includes adding appropriate labels, aria-attributes, and keyboard navigation support for the input field and submit button.

These changes do not introduce any breaking changes or new features. They are focused on improving the existing functionality and enhancing the overall user experience.
