Detox's logcat artifact is filtered to the app pid and written on-device with `logcat -f`, which is killed before it flushes its 4 KiB buffer. In CI both Expo flavours lost the last 5-24 s before the failure, and the filter drops system_server output, so an ANR could never show up. Run the Detox command through a wrapper that streams the unfiltered main/system/crash buffers to e2e-artifacts/logcat-full.txt from the host, so it is uploaded with the other failure artifacts.

Follow-up to #466. The logcat Detox saves was cut off right before the failure and only included the app's own process, so system logs like ANRs never showed up.
Now we also record the full logcat from the runner into
e2e-artifacts/logcat-full.txt. Tested with a forced failure on both Expo flavours: the log goes past the failure and includes system logs.
