Description
Automated testbook script that validates the full portrait pipeline on a body:
1. Set orientation to portrait via experience library API
2. Wait for hydrabody tick to sync
3. Verify Sunshine config has VDD output_name
4. Verify Sunshine app cmd has -windowed -ForceRes
5. Start stream, verify capture size 1080x1920 in Sunshine logs
6. Restore landscape
Catches regressions without manual testing. Should be runnable from neoremote via hydracluster exec.
