Stop Tailwind scanning ref strings, colour links in the user bubble

Tailwind read ref literals like [file:12] in prompts and docs as arbitrary-property utilities and emitted invalid CSS; those files hold no className, so they are excluded from the scan. Links in the user's ink bubble get a readable blue instead of the bubble's own ink, and the bubble no longer needs its own CSS class.
