Declare applications with one deferred configuration factory

Declare applications with one deferred configuration factory复制锚点链接

Applications now default-export defineHostApplication(startup => ({ ... })) from @pluxel/host. The factory returns the complete application configuration, synchronously or asynchronously; plain application exports and nested configure merging are removed. Each Host receives a shallow immutable startup snapshot shared by its factory and prepare callback. The helper preserves the inferred factory result and checks unsupported top-level fields.

Keep development and production assembly consistent复制锚点链接

Builds inspect inline factories without executing them and reject production plugin catalogs that cannot be resolved statically. Module-level and imported constant plugin arrays remain supported. Explicit environment and file bindings are described in the unified configuration change.

Re-evaluating an application factory replaces its Host; fixed-catalog execution reports this as host-reload. Dynamic source-only updates retain catalog HMR when the application factory is unchanged. Factory evaluation failures retain the running Host; failed replacement preparation recreates a Host from the previous successful factory. The starter and application documentation use the same factory declaration.
