Issue Overview

Many Angular / Nx workspaces keep their compiler options in tsconfig.app.json, while the root-level tsconfig.json only contains build references.

typescript-language-server starts tsserver with its default project discovery logic, so it always loads the nearest file literally named tsconfig.json and ignores the options in tsconfig.app.json. This leads to incorrect diagnostics, auto-imports and inlay hints inside the editor.

Expected behaviour

Provide a way, CLI flag, initializationOptions, or automatic detection, for the language server to ask tsserver to treat tsconfig.app.json (or any user-specified filename) as the primary project file.

Actual behaviour

No such override exists. The server loads tsconfig.json and never reads the settings in tsconfig.app.json.
