tsgo/TypeScript 7.0での変化

◎独自プロトコル ら標準のLSPへ移行中[1]
While most of the core type-checking code has been ported over without any behavioral differences, the
language service is a different story. Given the new architecture, much of the code that powers
completions, hover tooltips, navigation, and more, has been heavily rewritten.
Additionally, TypeScript 7.0 uses the standard LSP protocol instead of the custom TSServer protocol, so
some behavior specific to the TypeScript VS Code Extension may have changed.
