VS Code Markdown Language Server

The `vscode-markdown-languageserver` is a Node.js-based language server providing rich Markdown language support, including features like link completions, smart folding, document and workspace symbol navigation, document linking, renaming across files, code actions (e.g., organizing link definitions), and pull diagnostics for link validation. Currently at version `0.5.0-alpha.13`, it is actively developed, serving as the backend for VS Code's native Markdown capabilities. It operates as a standalone executable, communicating via the Language Server Protocol (LSP). The server leverages the `vscode-markdown-languageservice` for its core logic, which is recommended for developers needing a direct library for Markdown processing rather than a full LSP server. Its release cadence is tied to VS Code's development, with an 'alpha' tag signifying ongoing evolution and potential API changes.
