refactor(copilot): dedup getDocumentFormatInfo across copilot file tools

The same extension -> { formatName, sourceMime, taskId } mapping was
duplicated in workspace-file.ts and edit-content.ts. Any future format
or task-id change had to happen in two places.

Exports getDocumentFormatInfo + DocumentFormatInfo from workspace-file.ts
(which already owned the PPTX/DOCX/PDF source MIME constants) and
imports it in edit-content.ts. Same source-of-truth pattern the file
already uses for inferContentType.
