Summary of Changes

Added scene-centric ecosystem view:

/scene/:scene_id route renders one scene across all 19 themes
Each theme rendering links to its detail page for drill-down
Nav bar now includes scene links (Shell Prompt, Git Diff, etc.) for quick access
Enables side-by-side comparison of how themes handle the same terminal context
