feat(sheets): add +get-revision shortcut

Return a spreadsheet's current document revision without pulling the full
sub-sheet listing. +get-revision is a read-only derivative over
get_workbook_structure (the lightest read — token only, no range) that
projects the response down to the single revision field.

Adds flag-defs entries and a unit test for the projection helper.
