Refactor plugin loader and runner to support enhanced manifest structure

- Updated the PluginMeta class to utilize a strongly typed PluginManifest, improving type safety and clarity.
- Refactored dependency extraction logic to streamline the handling of plugin dependencies.
- Modified the PluginLoader to accommodate new manifest versioning and validation processes.
- Enhanced the PluginRunner to work with a dictionary for external available plugins, allowing for version mapping.
- Updated built-in plugins' manifest files to version 2, adding URLs and SDK versioning for better integration and documentation.
- Improved error handling and logging for plugin loading and dependency resolution processes.
