CliHost.RunWithTerminalGuiAsync ignores CommandKind - input clets run full-screen instead of inline

[tig]

Bug

CliHost.RunWithTerminalGuiAsync always creates a full-screen IApplication regardless of command.Kind. Input clets (CommandKind.Input) are specified to render inline by default (see clet spec §4.5: "Input clets render inline. Viewer clets render fullscreen. --fullscreen forces fullscreen for input clets").

After the port to Terminal.Gui.Cli, running e.g. clet select --options "foo, bar" goes full-screen instead of rendering inline beneath the cursor.

Root cause

CliHost.cs line ~170:

private async Task<CommandResult> RunWithTerminalGuiAsync (ICliCommand command, CommandRunOptions runOptions,
    CancellationToken cancellationToken)
{
    using IApplication app = Application.Create ().Init ();
    return await command.RunAsync (app, runOptions.Initial, runOptions, cancellationToken);
}

This never checks command.Kind or runOptions.Fullscreen. It should set Application.AppModel before calling Application.Create() based on:

1. command.Kind == CommandKind.Viewer → AppModel.FullScreen
2. command.Kind == CommandKind.Input and runOptions.Fullscreen == true → AppModel.FullScreen
3. command.Kind == CommandKind.Input and runOptions.Fullscreen == false → AppModel.Inline

Expected fix

Something like:

private async Task<CommandResult> RunWithTerminalGuiAsync (ICliCommand command, CommandRunOptions runOptions,
    CancellationToken cancellationToken)
{
    bool useInline = command.Kind == CommandKind.Input && !runOptions.Fullscreen;
    Application.AppModel = useInline ? AppModel.Inline : AppModel.FullScreen;

    using IApplication app = Application.Create ().Init ();
    return await command.RunAsync (app, runOptions.Initial, runOptions, cancellationToken);
}

Impact

All 14 input clets in gui-cs/clet regressed to full-screen rendering after the Terminal.Gui.Cli port. This is a v0.5 blocking issue per the spec milestones ("inline rendering verified on four-terminal matrix").

Repro

clet select --options "foo, bar"
# Expected: inline prompt below cursor (like fzf --height or gum choose)
# Actual: full-screen TUI
