fix: align the suite with the site layout

The redesign moved the technical questions to technical-faq.md, made the Get your files rows generated from each platform key and reduced getting-started.md to links. Tests now read those places: the pack-row test reads the rendered page. The new site scripts go through run_cli and refuse abbreviated options. The three maintenance image tools are exempt by name from the build dependency rule: their output is committed and the build only reads it. siteguides.py now triggers the site deploy, and the recipe counts match the store.
