chore(assets): reorganise project files and add exported pages
- Move Bootstrap Studio design file into assets/bootstrap - Rename and relocate screenshots into assets/screenshot with kebab-case names - Add generated export HTML pages for simulators and site content - Preserve existing content with no functional changes to simulators Signed-off-by: Alexander Davis <alex@adcm.uk>
