Overview

The JSON-RPC server loop.

Reads LSP messages from stdin, dispatches them to handlers, and writes responses and diagnostics back to stdout — the standard stdio LSP convention. All compatibility analysis is delegated to the browsable gem; this class only speaks the protocol.

  # STDIN/STDOUT); passing $stdin/$stdout keeps the default behaviour while
  # letting tests drive the server over StringIO pipes.
