Watch doesn't auto-build dependents

[SarahIsWeird]

Imported files do not trigger rebuilds on their dependents. This probably isn't easy to implement, but it would be an amazing QoL feature.

Steps to reproduce:

// src/lib/myLib.ts
export const myValue = 42;

// src/scripts/test.ts
import { myValue } from "../lib/myLib";
export default function (c, a) {
  return myValue;
}

$ hsm push src/scripts --watch

>>#up test
>>test
Success
42

// src/lib/myLib.ts
export const myValue = 69;

>>#up test
>>test
Success
42
