Function delete_all_content

atomic-core/src/record/workflow/globalize/hunk.rs:579–593

Build an [`EdgeUpdate`] that marks every content vertex in the file as deleted. This is the single place where "find all content vertices → create deletion edges" happens. Both [`globalize_replace_whole_file`] and [`globalize_delete`] delegate here. Uses [`find_content_vertices_global`] — the full SCC-aware traversal via `retrieve_graph`, the same one used for display/diffing — rather than a lin
