Every public action now has <summary>, <param>, and <returns> XML docs
plus matching SwaggerOperation/SwaggerResponse attributes with typed response
descriptions. Class-level summaries added to CvController, JobSearchController,
and RagController. Explanatory inline comments removed from FileDownloadController
per project conventions.
