- Added highlighters for new languages (SQL, Erlang, Forth) with filetype recognition. - Updated and reorganized syntax files to maintain consistency and modularity. - Introduced LSP transport framing unit tests and JSON decoding/dispatch tests. - Refactored `LspManager`, integrating UTF-16/UTF-8 position conversions and robust diagnostics handling. - Enhanced server start/restart logic with workspace root detection and logging to improve LSP usability.
