Description

Adds an optional boxShadow field to ChatBubble and wires it into TextMessageView’s BoxDecoration for outgoing and incoming bubbles when set.

Existing behavior: Text bubbles only supported color, borderRadius, border, padding/margin, etc.; there was no supported way to add a drop shadow without forking.

This PR: When boxShadow is null (default), appearance is unchanged. When set, the configured List<BoxShadow> is applied to the text message bubble.

Motivation: Allows apps to add subtle elevation/shadow for readability and visual hierarchy without patching the package.
