Streaming Markdown Parser

stream-markdown-parser is a pure JavaScript Markdown parsing and rendering utility library designed with streaming capabilities and framework-agnosticism. Currently at version 0.0.86, it exhibits a rapid release cadence with frequent patch and nightly builds, indicating active development. The library provides core Markdown parsing logic, extracted from the `markstream-vue` project, enabling its use in any JavaScript or TypeScript project without direct Vue dependencies. Key differentiators include its lightweight footprint, extensibility via a plugin-based architecture, comprehensive TypeScript support for type safety, and optimized performance for progressive, stream-friendly parsing. It is built upon `markdown-it-ts`, a TypeScript-first distribution of `markdown-it`, maintaining API compatibility while offering richer token type definitions for developers.
