+/**
+ * CivicNav — Civic Diagnostics section navigation widget.
+ *
+ * Renders in right_aside on:
+ *   - /channel/{assoc-slug}   — via load_pdl hook injected by vs01_load()
+ *   - /vs01/{assoc-slug}      — via mod_vs01.pdl
+ *   - /dsc01/{assoc-slug}     — via mod_dsc01.pdl
+ *   - /scn01/{assoc-slug}     — via mod_scn01.pdl
+ *
+ * Reads addon/vs01/civicnav.json for the registered addon list.
+ * Slug is resolved from the URL (argv(1) for addon modules) or from
+ * App::$profile['channel_address'] for the channel module.
+ * URLs use z_root() so they survive Zot6/Nomad channel migration.
+ *
+ * Returns empty string if no slug or slug not in vs01 config.
