This commit adds support for the Monarch language system, including the implementation of MonarchGrammarDefinitionDSL for grammar definition, and updates to the language-monarch module to handle language loading and configuration. Theme support for Monarch is also introduced, allowing for dark and light mode theming consistency with TextMate.
Themes now load colors asynchronously, which prevents blocking the main thread when parsing and applying theme settings. This optimization enhances the overall performance andresponsiveness of the application when switching or initializing themes. The TokenTheme adapter was updated to handle the asynchronous loading of theme colors. MonarchColorScheme was modified to apply themes more efficiently, especially when dealing with legacy TextMate themes. Additionally, the theme registration and management logic was refactored to ensure themes are loaded only when necessary.
…kens Adjust the theme loading function to collect colors into a map when provided with a nullthemeColorsMap. This change simplifies theme loading logic and avoids unnecessary skipping of values. Additionally, modify the token color reading function to add a default empty token, ensuring that at least one token is always present. This prevents potential runtime issues due to empty token lists.
consistency and adhere to coding standards.
…x implementation Update the regex libraries to the latest versions and modify the implementation in the MonarchLanguage class to support the additional regex features. Additionally, refactor the JSON parsing logic in the AutoClosingPairConditional loading process for better clarity.
- Remove unnecessary logging statements in AsyncIncrementalAnalyzeManager to clean up the code. - Adjust if-statement formatting for consistency and better readability. - Eliminate unused code segments in JsonParseTests and adjust import statements. - Ensure consistent code formatting across the specified files for enhanced maintainability.

This PR introduces the monarch to sora-editor.
Introduction
Monarch is a lightweight, declarative lexical specification-based syntax highlighter designed by the VSCode development team. The main purpose of introducing this library is to leverage Monarch's concise syntax definition and loading speed. Compared to the TextMate module, it offers a 10% - 40% speed advantage when rendering large text code, making it suitable for scenarios that don't require complex highlighting effects but desire dynamically loaded syntax highlighting with a certain level of speed.

This PR also implements VSCode theme loading and grammar repository abstraction, which may be useful in the future when rewriting the
lang-textmatemodule to Kotlin implementation.
