feat: CEP panel UI overhaul — Studio Shell redesign, new feature cards, transcript timeline

Major Codex-driven frontend refresh: redesigned alert banners with eyebrow labels and
inline SVG icons, quick action buttons with icon+meta layout, transcript timeline ruler,
emotion highlights and depth map feature cards, expanded CSS with Studio Shell pass
(responsive breakpoints, 4px spacing rhythm, complete interactive states). Added
requirements-lock.txt and gitignored installer build artifacts.
