✨ Feature Request: Add support for clearing the screen in TUI mode (e.g. Ctrl+K or similar)

[sumana]

Goals

When running turbo run ... --ui=tui, there's currently no way to clear the terminal screen or scrollback buffer. Common terminal shortcuts like Ctrl+K, Ctrl+L, or even typing clear do not work, since Turbo TUI uses a custom UI layer.

This becomes problematic when:

• Logs become noisy during long dev sessions
• You want to visually isolate a specific app's output or a fresh task run
• You want to clean up without restarting the TUI session

Expected Behavior:
A keyboard shortcut (e.g., Ctrl+K, Cmd+K, or L) should:

• Clear the screen for that specific task

This behavior is consistent with many developer tools, including:
Standard terminal emulators (macOS Terminal, iTerm, VS Code)

Other workarounds we tried:
We've already tried some workarounds (see below), but devs really prefer clearing the terminal while turbo is running with tui:

• Ctrl+C and re-running the command
• Using filters (--filter=my-app) to reduce log noise
• Switching to --no-ui (stream) mode

Non-goals

No response

Background

Adding this would improve the dev ex significantly when working with many apps or long-running sessions. It would also bring Turbo TUI in line with terminal expectations, helping adoption.

Thanks for the awesome work on TUI mode, this feature would make it even better!
