// Mounts pages contributed by client plugins. The host's
// `<ExecutorPluginsProvider>` (set up at the root) materialises the
// list of `ClientPluginSpec` from `virtual:executor/plugins-client`,
// and this route reads it via `useClientPlugins()` — so adding a
// plugin to `executor.config.ts` is sufficient for its pages to mount
// here, with no per-route imports.
//
// Match logic is intentionally tiny: exact path equality between the URL
// remainder and a `PageDecl.path`, with `""` and `/` treated as the
// same root. Plugins that want parameterized paths can build their own
// in-component routing for now.
