CLI does not exclude testing contracts & exclude option broken

Describe the bug

Using a pretty straightforward wagmi.config.ts:

export default defineConfig({
    out: "src/generated.ts",
    contracts: [],
    plugins: [
        react(),
        foundry({
            project: "../contracts",
        }),
    ],
})

The generated file contains abis & hooks for testing contracts that it should exclude by default (according to this). e.g.

export const scriptAbi = [
  {
    type: 'function',
    inputs: [],
    name: 'IS_SCRIPT',
    outputs: [{ name: '', internalType: 'bool', type: 'bool' }],
    stateMutability: 'view',
  },
] as const

I am testing this with only a single empty contract, as well as dummy test and deploy script, both of which should be excluded on the basis of the .s.sol and .t.sol extensions.

I've tried to work around this by setting the exclude option inside the foundry plugin, but I have never gotten it to do anything at all.

e.g.

export default defineConfig({
    out: "src/generated.ts",
    contracts: [],
    plugins: [
        react(),
        foundry({
            project: "../contracts",
            exclude: [
              "Main.sol/Main.json",
            ],
        }),
    ],
})

will still include the ABI for my Main (empty contract, not imported anywhere).

Trying broad exclude patterns like *.json or **/*.json also produces no changes whatsoever.

The way I remember this worked in previous versions is that I used the include option to only specify my own contracts, and it would generate the ABI & hooks only for those. That doesn't work anymore either.

Unrelated to the issue at hand, but I also think the contracts option is super confusing as it requires specifying ABI, which wagmi should be able to pull out from the artifacts itself.

My understanding is you don't need to specify any contract there, but that isn't clear from the docs. I'm also unsure about the use case — generating hooks for contracts whose ABI you have but whose code isn't in your contracts repo (and so the ABI does not get generated by foundry)?
