rintenki HTML LSP Server

rintenki-lsp-server is a Language Server Protocol (LSP) implementation specifically designed for the rintenki HTML linter. It provides real-time diagnostics, code actions (including quick fixes for auto-fixable rules), and rich hover information for HTML documents. Currently at version 0.14.5, it is under active development, likely with a release cadence tied to the core rintenki linter. Key differentiators include its focus on precise HTML linting, integration with the robust rintenki ruleset, and configurability via a `.rintenkirc.json` file or editor-specific settings. While primarily consumed by editor extensions like the rintenki VS Code extension, it can be integrated with any LSP-compatible client by launching it as a standard I/O process.
