markdown-it Emoji Plugin

markdown-it-emoji is a plugin for the `markdown-it` markdown parser, providing comprehensive support for emoji and emoticon syntax. It parses both standard Unicode emoji shortcodes (e.g., `:smile:`) and common emoticons (e.g., `:)`, `:-(`), converting them into their respective Unicode characters by default. The current stable version is 3.0.0. While no explicit release cadence is stated, it follows the `markdown-it` ecosystem, generally releasing new major versions to align with significant changes or improvements. Key differentiators include its tight integration with `markdown-it`'s plugin architecture, offering configurable emoji sets (full, light, bare), and allowing custom rendering functions for integration with libraries like Twemoji or custom icon fonts. It handles both ESM and CommonJS environments, with specific export changes introduced in v3.
