Bone Setup Automation (Detail Bones)

🔍 Problem
Manually building complex bone setups beyond the default Biped structure every time is inefficient.

💡 Requested feature
Automatically add, wire, and set up detail bones on a Biped base — similar to the BipedPlus automated rigging tools currently in development.

🎯 Expected benefit
Enable solid character setup without a dedicated rigger — especially useful for small teams and solo creators.
