Add setup-phoniebox: Raspberry Pi RFID jukebox setup workflow

[RazHadas]

Summary

• Adds a complete end-to-end workflow for setting up Phoniebox v2 — a popular open-source RFID jukebox for Raspberry Pi
• Handles all remote work via SSH so the user never needs to type on the Pi directly; works from Windows, Mac, or Linux
• Documents every real-world pitfall discovered during an actual setup, with exact fixes

What it covers

1. Hardware checklist and SD card flashing (Raspberry Pi Imager settings)
2. SSH key authentication via Python paramiko (works on Windows without sshpass)
3. Non-interactive Phoniebox installation using PhonieboxInstall.conf
4. Post-install fixes: evdev module, MPD volume normalization, startup volume, ALSA PCM on boot
5. RFID reader detection and deviceName.txt registration (critical printf vs echo note)
6. udev rule for auto-restart on USB reconnect
7. YouTube audio downloading via yt-dlp with Node.js JS runtime
8. RFID card-to-folder and card-to-command registration
9. Full health-check command and troubleshooting table

Test plan

• Workflow file renders correctly in Claude Code as /workflows:setup-phoniebox
• All bash commands are syntactically valid
• Troubleshooting table covers the most common failure modes
