Walkthrough

This update introduces major refactoring and modularization of the rich text editor in the Snow Leopard app. Core editor logic, plugin management, formatting state tracking, diff preview, inline suggestions, and save handling are moved into dedicated modules. Several new plugins and utility functions are added, and obsolete or redundant code is removed for clarity and maintainability.

Poem

A hop, a skip, a modular leap,
The editor’s logic, now tidy and neat!
Plugins for diff, for save, for style,
Suggestions stream in, making rabbits smile.
Out with the clutter, in with the flow—
Snow Leopard’s editing, ready to go!
🐇✨
