fix: restore Todos and Roadmaps plugin nav entries via manifest dashboardViews

Both plugins declared dashboardViews only in their src/index.ts module.
PluginLoader.getCurrentManifestDashboardViews treats a successfully-read
manifest as authoritative and returns an empty list when the key is absent,
and getPluginDashboardViews only falls back to the module definition when the
manifest read fails. The module-level entries were therefore discarded and
neither view appeared on any nav surface -- header overflow, desktop sidebar,
or mobile More sheet all consume the same array from usePluginDashboardViews.

Mirror the manifest shape used by fusion-plugin-compound-engineering.

+dev: Both plugin `manifest.json` files were missing the `dashboardViews` block that `PluginLoader.getPluginDashboardViews` treats as authoritative, so the module-level `dashboardViews` in each `src/index.ts` was discarded and the views were absent from every nav surface.
