Summary by Sourcery

Enable formula support in CherryMarkdown by introducing a UseKatex flag that loads KaTeX assets and configures the markdown engine, while upgrading to cherry-markdown.core.js and consolidating editor options.

New Features:

• Add UseKatex parameter to enable math formula rendering via KaTeX in CherryMarkdown component
• Lazy-load KaTeX JS and CSS assets when UseKatex is enabled

Enhancements:

• Switch to using cherry-markdown.core.js and spread all options into the editor initialization
• Remove individual option assignments in favor of spreading the options object

Reviewer's Guide

Upgrades the CherryMarkdown component to leverage the new core build, streamline initialization with spread options, and optionally render mathematical formulas via KaTeX when the new UseKatex flag is enabled.
