Add author auth, forking, tags, and stats tracking

Introduce token-based author authentication (register/verify API),
   skill forking with EditGate protection, tag metadata on skills,
   and download/push stats. Enhanced push scripts with token auth
   and per-skill filtering. Updated UI with stats, tags, and
   author info on skill cards.
