hashTypedData does not check domain type at runtime

Viem Version

2.21.44

Current Behavior

Good afternoon!

I can pass any value as domain to the hashTypedData function and it will be hashed regardless without checking its type at runtime.

    hashTypedData({
      ...typedData.complex,
      domain: 'wrong' as unknown as Record<string, unknown>,
      primaryType: 'Mail',
    }),

The equivalent in ethers does check the value at runtime.

Expected Behavior

I get an error since I am trying to fool the function and the hash that I get as a result does not take the domain into account (might be just an error on my side).

Steps To Reproduce

Run pnpm vitest run src/utils/signature/hashTypedData.test.ts -t 'wrong domain value' on this forked branch: https://github.com/freemanzMrojo/viem/tree/test-hash-typed-data (it uses the code above).
