Enable Markdown Support in `chat_view` Package

[jay23794]

Is your feature request related to a problem? Please describe.
Yes, the chat_view package does not support rendering of markdown text. I'm often frustrated when I try to display formatted messages with markdown (like bold, italic, links, or code blocks), but they appear as plain text instead.

Describe the solution you'd like
It would be great if the chat_view package could natively support rendering markdown text, so that messages with markdown formatting are displayed correctly in the chat interface.

Describe alternatives you've considered
As an alternative, I've tried preprocessing the markdown text into HTML or plain text, but this is cumbersome and inconsistent, especially for complex markdown structures.

Additional context
Adding markdown rendering support would improve the readability and user experience significantly. If possible, supporting common markdown features such as headings, lists, links, and code blocks would be ideal.
