[Feature Request / UX Issue] DarkGrey color used in confirmation dialogs is not visible on Solarized dark Terminal theme

When using Solarized Dark theme in iTerm2, the text printed used DarkGrey colour which primarily used for confirmation dialogs is not visible. DarkGrey color has low visibility in dark themes, and this issue will also impact other popular low contrast themes. The text is only visible when you select the region in the terminal. Please see the screenshot below.

After selecting the region in the terminal.

This particular issue is caused by the use of DarkGrey colours on line 1184 - 1205 of src/cli/chat/mod.rs file, through DarkGrey color is extensively used in other places.

``` Rust
if show_tool_use_confirmation_dialog {
execute!(
self.stderr,
style::SetForegroundColor(Color::DarkGrey),
style::Print("\nAllow this action? Use '"),
style::SetForegroundColor(Color::Green),
style::Print("t"),
style::SetForegroundColor(Color::DarkGrey),
style::Print("' to trust (always allow) this tool for the session. ["),
style::SetForegroundColor(Color::Green),
style::Print("y"),
style::SetForegroundColor(Color::DarkGrey),
style::Print("/"),
style::SetForegroundColor(Color::Green),
style::Print("n"),
style::SetForegroundColor(Color::DarkGrey),
style::Print("/"),
style::SetForegroundColor(Color::Green),
style::Print("t"),
style::SetForegroundColor(Color::DarkGrey),
style::Print("]:\n\n"),
style::SetForegroundColor(Color::Reset),
)?;
}
```

One possible option would be to use the default colour for the text, except for "[y/n/t]" within confirmation dialogs. Happy to discuss options as well.

Inizia in src/cli/chat/mod.rs intorno alle righe 1184–1205 e riproduci la finestra di dialogo di conferma con il tema Solarized Dark di iTerm2. Esamina gli usi di DarkGrey in quella finestra di dialogo e nello stile di conferma correlato. Il lavoro è completato quando il testo della finestra di dialogo è leggibile su temi scuri a basso contrasto e le opzioni y/n/t rimangono distinguibili.

Scritto dal modello di indicizzazione a partire dal testo della issue.
