Our editor interaction for running `go generate` was untested. Add support for triggering generate from the fake editor, and a simple test. To enable this, some helpers were added to list Workspace files and check for file state changes, to avoid having to synthetically create file events. This workaround is not ideal as it results in a leaky abstraction: in other cases the regtest may assume that FileEvents are triggered by workspace interactions (e.g. ws.WriteFile), but in this case it cannot. Unfortunately the only real solution for this would be to make file watching more realistic, by polling file state on an interval or using an actual file watching library. Neither of those options seemed worthwhile just to keep the fake.Editor API pristine. A new debugging option is added, SkipCleanup, to allow inspecting regtest working directories after a test with minimal code change.
