End-user friendly description of the problem this fixes or functionality this introduces.

Fixed an issue where user-entered bash commands would appear twice in the terminal. Now, when you type a command in the terminal, it will only be displayed once, providing a cleaner and more consistent experience.

Summarize what the PR does, explaining any non-trivial design decisions.

This PR fixes a bug where user input bash commands were being echoed twice in the terminal:

1. First as the user types it (expected behavior)
2. Then again when the command is sent to the backend and added to the commands array

The solution modifies the renderCommand function in use-terminal.ts to skip rendering user input commands that have already been displayed as the user typed them. This is done by adding an isUserInput parameter to the function that, when true, will skip rendering commands of type "input".

Design decisions:

• Added an optional parameter to the existing function rather than creating a new function to minimize changes
• Used a simple type check to determine whether to render the command, making the solution straightforward and maintainable
• Updated both initialization and update rendering paths to ensure consistent behavior
