fix(command-bar): move cursor to end of input after typing

This commit addresses issue #286 by improving the cursor behavior within the command bar.

Previously, the cursor remained fixed after the command prompt, even as the user typed input. This has been corrected so that the cursor now dynamically moves to the end of the input text as the user types, providing a more intuitive and user-friendly experience.

Closes #286
