Frame interactive inputs and demo update

[joejollands]

Motivation

• Ensure interactive inputs (text prompts, select, radio, multi-select) render inside TART’s themed framed canvas using the active theme’s colors and stable visual-length padding.
• Replace full-screen clears with cursor-scoped redraws limited to the input’s framed region to avoid wiping the whole terminal and preserve surrounding output.
• Unify framing behavior so highlighted rows use theme-driven highlight/text colors and long/ANSI/emoji labels remain visually aligned.
• Provide a short interactive demo tweak to showcase framed text input in action.

Description

• Add a new FrameRenderer helper (src/Support/FrameRenderer.php) that composes framed lines and provides format(), writeln(), writeStart(), and writeFinish() helpers using the active ThemeInterface and LineFormatter for visual-length aware padding.
• Update HasEnhancedInput (src/Concerns/HasEnhancedInput.php) to frame prompt() and password() using FrameRenderer::writeStart()/writeFinish() so typed input appears inside the framed canvas.
• Update InteractiveMenu, Select, and MultiSelect (src/Support/InteractiveMenu.php, src/Support/Select.php, src/Support/MultiSelect.php) to accept an optional ThemeInterface, construct a FrameRenderer, render options through it, apply theme highlight/text colors, and replace full-screen clears with TerminalControl::moveUp() plus scoped clears.
• Propagate theme through helpers by updating HasInteractiveMenus and HasSelect (src/Concerns/HasInteractiveMenus.php, src/Concerns/HasSelect.php) to pass $this->getTheme() when instantiating interactive classes.
• Add the TUI frame design spec documentation at docs/guides/TUI-FRAME-SPEC.md describing layout, rendering rules, and the plan for framing interactive inputs.
• Update the interactive demo command (src/Laravel/Commands/TartInteractiveDemoCommand.php) to mention framed inputs, add a framed prompt() for a run name, and include the run name in the summary.

Testing

• No automated tests were run for these changes.
