fix: gracefully degrade when LS fails to start

Tomas Vik (OOO back on 2026-08-31)requested to merge
tv/2025-05/handle-ls-failure into main

Description

This small MR introduces a timeout for the LS to start (10 seconds).

If the LS fails to start, the rest of the extension keeps working.

Before this change, the extension would hang indefinitely if the LS fails to start.

This MR is more for local development purposes, I don't expect total LS failure in production since we have it covered by tests.

How has this been tested?

  1. Connect LS to the VS Code Extension
  2. Break LS by, for example, removing a necessary DI dependency from the contributinos.ts
  3. Start the extension
  4. Before the extension initialization hang indefinitely, after the MR, the initialization finishes without the LS
