Add guided first-edit activation

[a-baran-orhan]

Summary

• add a dismissible guided first-edit card on /play/superhero-landing
• focus the existing knee_right direct angle control, switching to Editor on mobile
• show a concise success state with Share only after a user edit produces a valid custom render
• add privacy-safe experiment analytics and focused desktop/mobile, dismissal, completion, and wiring tests

Why

The default playground path currently demonstrates a finished movement but does not give new visitors a concrete first action. This experiment offers one bounded edit that uses the existing deterministic editor and renderer architecture, without adding generation, authentication, hosted services, or broad onboarding.

Validation

• npm test — 449 tests passed across 46 files
• npm run typecheck
• npm run build
• production-build visual QA at 1440×900 and 390×844, covering focus, mobile Editor switching, valid-render success, Share state, and dismissal

Analytics payloads contain only the fixed experiment identifier, surface, and stage; Posecode source, angle values, URLs, and personal identifiers are not sent.
