Subject: [PATCH] perf(layouts): eliminate N+1 site.GetPage lookup for authors

Pre-computes a map of author pages to their titles outside the main
loop in `layouts/index.json`. This replaces an O(N) lookup inside the
loop with an O(1) dictionary lookup, dramatically improving search
index generation speed for large sites.
