Subject: [PATCH] Fix breadcrumb navigation for directories

- Breadcrumb items for directories are now only clickable if an index file exists
- Prevents 404 errors when clicking on folder names in breadcrumb
- Non-clickable directory items are shown as active text
- Improves navigation UX and prevents broken links
