Module formatting 

Text formatting for emoji and markdown processing.

This module provides transformation of ASCII emoticons to Unicode emoji and basic markdown formatting (bold, italic, code) with Ratatui styling.

Supported ASCII Emoticons

The following ASCII emoticons are automatically converted to Unicode emoji:

ASCII	Emoji	Description
(y)	👍	Thumbs up
:-)	😊	Smile
:)	🙂	Simple smile
:-D	😄	Grin
:D	😄	Grin
;-)	😉	Wink
;)	😉	Wink
:-P	😛	Tongue
:P	😛	Tongue
:-(	😞	Sad
:(	😞	Sad
:/	😕	Unsure
:o	😮	Surprised
:O	😮	Surprised
:*	😘	Kiss
:|	😐	Neutral
:Q	👶	Baby face

Markdown Formatting

• *bold text* - Renders in bold
• _italic text_ - Renders in italic
• `code` - Renders with code styling (reversed video)

Important: Content within backticks is treated as verbatim text. No emoji replacement, bold, or italic formatting will be applied inside backtick pairs. For example:

• `*not bold*` - The asterisks remain literal
• `:) no emoji` - The emoticon remains as :)

Processing order ensures backticks are handled first, protecting their content from all subsequent transformations.
