Chaining doesn't bail out

If you have:

```go
expect("a").
To.Equal("b").
And.Pass(SomeMatcher{}) // <- Should this not run?
```

I wouldn't expect the `And.Pass(...)` to be invoked.

Look at the chaining logic in the expect package, likely in the main assertion methods. Understand how the chain is evaluated and where bail-out should occur after a failure. Check existing tests for chaining behavior to see the expected flow. The fix involves modifying the chain to stop evaluating subsequent matchers after a failure.
