Problem Description

The only way to get a different font and/or colors are through two APIs, a string option for font, and ANSI color codes for color, which end up being buggy (see #29287 and #29288) and incompatible via these bugs.

Proposed Solution

Add a new API that lets me set the title via an array of objects with keys:

type CssCode = string;

type Segment = {
  text: string;
  bold?: boolean;
  fontName?: 'monospaced' | 'monospacedDigit';
  color?: CssCode;
};

class Tray {
  // ... existing methods

  setTitle(segments: (string | Segment)[]): void;
}

Something like that would easily map to NSAttributedString.

Alternatives Considered

None.

Additional Information

This would keep old setTitle() signature for backwards compatibility. It'd be a separate, new API.

Oh also it should have a bold boolean key. Updating the thing now to include that.

fontSize too would be amazing!
