Pull Request Overview
This PR refactors the plugin execution provider (EP) support by reorganizing code into a dedicated plugin_ep subdirectory. The primary goal is to improve code organization and make EP-related functionality easier to locate and maintain.
Key changes:
- Move all plugin EP-related files to a new
core/session/plugin_ep/directory - Split large monolithic implementation files into separate, focused class files
- Update all include paths to reflect the new directory structure
