Subject: [PATCH] Add support for renaming a tab

Add support for renaming tabs in the terminal application.

* **State Management:**
  - Add a new state variable `tabTitles` in `packages/terminal/app/page.tsx` to store tab names.
  - Modify the `createTab` function to initialize the tab name.
  - Modify the `closeTab` function to remove the tab name.
  - Pass the `tabName` prop to the `Tab` component.

* **Tab Component:**
  - Accept a `tabName` prop in `packages/terminal/components/Tab/index.tsx`.
  - Display the `tabName` in the tab.
  - Add an input field to allow users to rename the tab.
  - Handle the input change event to update the tab name.

* **TitleBar Component:**
  - Update the title bar in `packages/terminal/components/TitleBar/index.tsx` to reflect the renamed tab.
  - Use the `tabName` prop to display the tab name in the title bar.

* **TabContext:**
  - Add a function to handle tab renaming in `packages/terminal/hooks/TabContext.tsx`.
  - Update the context to include the tab renaming function.
