Merge goalie-tester worktree: modes, 3v3 goalies, OOB faceoffs, CF deploy.

Bring main menu (1v1/3v3), scrimmage with nets and goalies, dead-puck
whistles at the nearest faceoff circle, skater board re-entry, and
Cloudflare Workers/Pages deploy config. Keep main jersey gear stack and
compact goalie floaters.
