Summary of Changes

Hello @bajrangCoder, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the user experience within the terminal by dynamically managing the visibility of the quicktools toggler. The toggler will now automatically hide itself when the terminal input is active, preventing it from obstructing the view, and then gracefully reappear when the terminal input is no longer in focus. This change aims to reduce visual clutter and improve usability during terminal interactions.

Highlights

• QuickTools Visibility: The quicktools toggler now automatically hides when the terminal input gains focus and reappears when it loses focus.
• Terminal Input Focus Handling: Event listeners have been added to the terminal's textarea to detect focus and blur events, triggering the visibility changes for the quicktools toggler.
• Dependency Update: The quickTools component has been imported into terminalManager.js to enable its visibility control.

Code Review

This pull request adds functionality to hide the quick tools toggler when the terminal input is focused, and show it again on blur. This is a good user experience improvement.

My review focuses on a potential memory leak introduced by the new event listeners and a minor code style point. The main issue is that the added event listeners are not being cleaned up when a terminal is closed. I've provided a suggestion to refactor the code to allow for proper cleanup.
