feat: finish portfolio title, navigation, and destination effects

Add the approved name animation, rounded docking navigation, localized keyboard focus cue, unified builds card, and destination copy hierarchy.

Introduce lightweight one-shot meteors and a sun ring that repeats every three seconds at Contact. Open the email action in a separate browsing context. Preserve reduced-motion behavior and keep private handoff and visual-check artifacts out of version control.

Validation: 649 tests passed; all 20 failures in world-models and SceneCanvas reproduce on baseline 103427f. Typecheck, artifact verification, and transfer budgets passed. Client/SSR preview build passed before this commit. Existing baseline test failures remain unchanged.
