   “Submit” is the act of uploading, submitting, transmitting, or distributing code or other content to any
   Project, including but not limited to communication on electronic mailing lists, source code control
   systems, and issue tracking systems that are managed by, or on behalf of, the Project for the purpose of
   discussing and improving that Project, but excluding communication that is conspicuously marked or
   otherwise designated in writing by You as “Not a Submission.”
   “Submission” means the Code and any other copyrightable material Submitted by You, including any
   associated comments and documentation.
2. Your Submission. You must agree to the terms of this Agreement before making a Submission to any

3. Originality of Work. You represent that each of Your Submissions is entirely Your original work.
   Should You wish to Submit materials that are not Your original work, You may Submit them separately

   Submission is made in the course of Your work for an employer or Your employer has intellectual
   property rights in Your Submission by contract or applicable law, You must secure permission from Your
   employer to make the Submission before signing this Agreement. In that case, the term “You” in this
   Agreement will refer to You and the employer collectively. If You change employers in the future and
   desire to Submit additional Submissions for the new employer, then You agree to sign a new Agreement
   and secure permission from the new employer before Submitting those Submissions.

Pull request overview

This PR introduces an initial scaffold for a full-screen Terminal UI experience inside azure-cli-core, implemented with prompt_toolkit, and adds a new --terminal (and -t) entry path to launch it from az.

Changes:

• Added a TerminalApplication (prompt_toolkit.Application) and a set of basic UI panels (header/command/navigator/output/context).
• Hooked a new --terminal / -t argument check into AzCli.invoke() to launch the Terminal UI instead of executing a normal CLI command.
• Added a start_terminal() method on AzCli to run the TUI.

Reviewed changes

• toggle_recording() only flips self.recording, but the layout (including HeaderPanel(...)) is built once and never refreshed, so Ctrl+R won't change anything on screen. Consider wiring recording into the UI via a dynamic formatted-text control and triggering an invalidate/refresh when toggled.

                HeaderPanel('2.15.0', 'xiaojxu@microsoft.com', 'AzureSDKTeam'),
                CommandPanel(),
                VSplit([NavigatorPanel(), OutputPanel()], height=D()),
                ContextPanel()
            ], padding=0)),
