feat: attach a `CoverageInspector` to the `Executor`

### Describe the feature you would like

Feature: Getting coverage information from anywhere by attaching a `CoverageInspector` to the `Executor`.

I'm trying to find coverage during a run of a transaction, so I tried adding a `Coverage` Inspector to the `ExecutorBuilder`. I'm able to see that the `coverage` bool is set in the `Executor`, but after I run a transaction on the `Executor` and I run `collect` on the `InspectorStack` I get an empty `HitMap`.

I'm thinking that this is happening because the Analyzer is never called on the source contracts, so there are no `Anchors` but I'm not sure.

Let me know if this is out of scope or if it's already possible and I've missed something.

Thanks!

### Additional context

_No response_

Start by tracing how ExecutorBuilder attaches inspectors to Executor, then follow InspectorStack::collect and the Analyzer, Anchors, and HitMap flow described in the issue. Reproduce coverage collection during a transaction and determine where source contracts are analyzed; done means a CoverageInspector attached to an Executor produces coverage data rather than an empty HitMap.
