Add PWM-based servo control skill for RDK nodes with hardware servo support.
Changes:
- Add taiyang skill with SKILL.md and servo_dance.py script
- Update Dockerfile and Containerfile to include taiyang skill
- Update SOUL.md with skill constraints documentation
The skill controls two servos via /sys/class/pwm interface and must run on node side only.
