…openswarm-ai#136) serve_workspace_file and the workspace seed writer checked containment with a bare startswith(folder), so a sibling workspace whose id is a string prefix of the target (abc vs abc-evil) passed the guard. Match the stronger form already used by write_workspace_file/delete_workspace_file: startswith(folder_norm + os.sep) with the folder-itself equality escape.

Description
Fixes #136.
serve_workspace_file()and the workspace seed writer validated workspace containment using a barestartswith(folder)comparison. As a result, a sibling workspace whose ID was a string prefix of the target workspace (e.g.abcvs.abc-evil) satisfied the containment check, leaving these two endpoints inconsistent with the stronger validation already implemented bywrite_workspace_file()anddelete_workspace_file().Changes
serve_workspace_file()and the workspace seed writer to use the same directory-boundary check already employed by the write/delete endpoints:abcmatchingabc-evil.Validation
