dx: fix typescript slowness

As a ts developer, I want typescript to give me feedback immediately so that I can use its errors and hints to guide my understanding and increase the correctness of the code.

--

Original situation: Ts needs 11 seconds to check the code. With iterative checking, it's usually around 2-5s. it's almost completely unusable.

--

Acceptance criteria:

• In 95% of cases, typescript gives the developer feedback at the line I'm currently editing within less than 1s
• The solution works in vscode and zed
• Onboarding new developers is not hampered significantly by the solution to the compile-time performance
