Current topic: "Addressing Review Feedback - Implementation"
Topic summary: I am now addressing the specific issues raised in the PR review. This includes cleaning up app/build.gradle.kts (removing redundant checks, using tasks.named, inlining single-element lists, and fixing instrumentation args), removing the unrelated BillingManagerImplTest.kt, and updating documentation. I will also improve the screenshot capture verification and log unknown device dimensions.

Strategic Intent: Applying PR feedback to app/build.gradle.kts and related files.
