Current topic: "Fixing Gesture Nav and Device Aliasing"
Topic summary: I have identified two main issues: 1) Gesture navigation isn't showing up, possibly due to timing or the command not being forceful enough. 2) All devices are producing identical screenshots because GMD tasks seem to share the same instrumentation arguments instance, causing bucket aliasing. I will update `DemoMode.kt` to use both `settings` and `cmd overlay` for gesture navigation with a settle delay, and refactor `StoreScreenshotBase.kt` to use screen dimensions for reliable device/bucket detection. I will also unify the output directory to avoid further aliasing issues.

Strategic Intent: Fix gesture navigation and ensure correct screenshot generation per device.
