fix #3030 and run relateive test in edge-runtime

[promer94]

This pr intends to fix the inconsistent behavoir of swr's hash in edge-runtime dev mode.

The reason for this problem is because we're using node.js to simulate the edge-runtime for local development

The global Array and Object of edge-runtime are injected from node.js and the JS engine does not use global Array/Object constructor while building an array/object literal.

Then in dev mode

[].constructor !== Array.constructor
{}.construrtor !== Object.contructor

So we need find alternative to determine whether a key is an array or a plain object

Can you add a PR description and some comments about the change in hash? It's important for others to understand the approach and grab the context when they read the code later unless directly by reading the code

this should be dev dependency

can we keep the trailign line break for each file?
