Support memory static files and plugin APIs

Introduce in-memory static file support and inter-plugin exports. Add MemoryStaticFile/MemoryFileGenerator types and expose staticOnMem in PluginRouterRegistry; router registry now tracks memory routes and exposes getters. Add getPluginExports to plugin manager adapters to allow plugins to call each other's exported modules. WebUI backend gains routes to serve /plugin/:pluginId/mem/* (memory files) and /plugin/:pluginId/files/* (plugin filesystem static) without auth. Update builtin plugin to demonstrate staticOnMem and inter-plugin call, and add frontend UI to open extension pages in a new window. Note: API router no longer mounts static filesystem routes — those are handled by webui-backend.
