feat: cinematic UI/UX improvements and Creator Studio enhancements

[ruhdevops]

This PR implements a series of technical and UX improvements to bridge the gap between the public archive and the creator studio:

1. Unified Architecture: Replaced the 'Studio' button with a dedicated 'Viewer/Creator' mode toggle and added breadcrumb navigation for better spatial awareness.
2. Enhanced Discovery: Upgraded the search engine with fuzzy scoring to handle typos and implemented high-fidelity OKLCH shimmer skeletons for better perceived performance.
3. Workflow Visuals: Replaced static status lists with an interactive project stepper and added a Kanban board toggle for project management.
4. Creator OS Features: Added a 'Script-to-Scene' mapping tool that allows creators to link script highlights to references, and an SEO Heatmap to visualize metadata optimization.
5. Accessibility: Added Space and M keyboard shortcuts for the player and increased contrast ratios for the cinematic dark theme.
6. Scalability: Increased the items per page to 15 and optimized the responsive grid layout.
