+- Refactor internal checks API. This fixes duplication of some problems from the problems array, instead ensuring a single problem instance is visible from each relevant resolution.
+- Improve problem type API. Renames many fields on individual problem types.
+- Move module kind data off of `EntrypointResolutionAnalysis` and onto a top-level map in `programInfo`, a new top-level field on `Analysis`.
