Properly support Typescript 7

[No767]

Summary

Last year, Microsoft started to rewrite their Typescript compiler from Typescript to Go. Since then, it has been completed and has generally released since July 8, 2026. This major port had a lot of changes, which their API has been overhauled and planned to ship later. For now, the recommendation is to pin the typescript package to @typescript/typescript6, while allowing the @typescript/native-preview be used for the compiler itself. So, linters still get the Typescript 6 API, while we get the Typescript 7 compiler.
