GHSA-QF4G-9FQQ-MMM7 Absinthe: Unbounded atom creation from parsed directive name

Summary When Absinthe parses a GraphQL SDL document, every directive @ definition is converted into a freshly created atom without any allow-list or length cap. Because atoms are never garbage-collected and the BEAM has a hard 1,048,576 atom-table limit, any application that feeds...
