Summary

This PR publishes real viewport metadata across the supported adapters and improves live native-session visibility and assertion reporting.

• Adds shared viewport resolution for browser and native sessions and integrates it with WebdriverIO, Nightwatch, Selenium JavaScript, and Selenium Python.
• Buffers messages emitted while the dashboard socket is connecting and safely handles dropped messages.
• Adds live-mode native screenshots without duplicating trace-mode screenshot capture.
• Introduces a live-device workbench layout with usable action, dock, and capture panes.
• Correctly records negated WebdriverIO assertions while avoiding user-controlled prose false positives.
• Adds changesets and focused coverage for viewport metadata, socket buffering, native screenshots, and assertion outcomes.
