fix: increase stream-load-timeout to 6 seconds

@Asko-Dev reports that the `SteamLoadTimeoutError` seems to be thrown
"randomly" on iOS 17.5.1 ( see #298 ). That suggests that there is a race condition
with the timeout. Let's try to double the timeout (3s -> 6s) and see if
that helps.

Side changes:

* The ESLint setup is broken somehow and since linting is a pre-commit hook
  it blocks the committing process. Thus, removing the setup entirely for
  now. To be fixed later if deemed necessary.
* migrate legacy Nix setup to Nix flakes / direnv
