Add a public route to serve plugin extension pages without auth and update related pieces accordingly. Backend: register GET /plugin/:pluginId/page/:pagePath to locate the plugin router, validate page and HTML file existence, and send the file (returns appropriate 4xx/5xx errors). Frontend: switch iframe and new-window URLs to the new unauthenticated route (remove webui_token usage). Builtin plugin: clarify page registration comment and add a log line for the extension page URL. Minor formatting whitespace tweaks in plugin manager type annotations.
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.
Change plugin loader to treat plugins as disabled by default (unless the id/dir is 'napcat-plugin-builtin') by using nullish coalescing when reading statusConfig. Add an early-return guard in the plugin manager/adapter that logs and skips loading when entry.enable is false. This prevents disabled plugins from being loaded automatically and provides a clear log message when skipped.
Introduces a plugin router registry for registering plugin-specific API routes, static resources, and extension pages. Updates the plugin manager and context to expose the router, and implements backend and frontend support for serving and displaying plugin extension pages in the WebUI. Also adds a demo extension page and static resource to the builtin plugin.
Refactors the plugin manager by extracting configuration, loader, and type definitions into separate modules under the 'plugin' directory. Introduces a new PluginLoader class for scanning and loading plugins, and updates the main manager to use modularized logic and improved type safety. This change improves maintainability, separation of concerns, and extensibility for plugin management.
