internal/datadir now owns the DATA_DIR mode as an exported constant, DirPerm; internal/database consumes it in both places that create the directory rather than keeping its own copy. datadir is the owner because guarding and creating DATA_DIR is its whole purpose, and the dependency runs the right way: datadir imports only the standard library and the flock package, so database importing datadir adds no cycle. A comment on DirPerm names it as the single source, chosen over a source-scanning test because it survives refactoring and builds no machinery that inspects the tree. The mode value is unchanged.
