Subject: [PATCH] fix(tools): remove duplicate category nav on /tools/ hub

The static <nav aria-label="Tool categories"> was duplicating the six
category links already rendered by the ToolsHub client:load island.
The collapsible SEO prose block added in PR #25 made the duplication
visible; the plain nav has been removed so only ToolsHub remains.
