Fix ChittyID compliance violations - use @chittyos/chittyid-client

- Replace all crypto.randomUUID() calls with ChittyID service
- Replace all Math.random() ID generation with ChittyID service
- Update chittypass.js: User and password IDs now use ChittyID
- Update cross-session-sync: Session and version IDs now use ChittyID
- Update chittyrouter-gateway.js: Vector IDs now use ChittyID
- Update client-integration.js: Session IDs generated via service
- Update ai-github-bridge.ts: AI session IDs use ChittyID service

All ID generation now follows SERVICE OR FAIL principle.
NEVER generate locally - ALWAYS request from id.chitty.cc
