* test(replay-ui): pin keyboard-nav ownership and key routing

* test(replay-ui): pin metrics formatters and path gap handling

* refactor(sidecar): expose device-output parsers as internal for testing

* test(sidecar): table-test device-output parsers against malformed input

* test(sidecar): cover logcat parsing year inference and line skipping

* test(sidecar): pin pressKey keycode mapping and unknown-key rejection

* test(sidecar): metrics bundleId falls back to launched app and honors override
