Default Negation for Non-Guarded Existential Rules

Summary: Extend sticky (non-guarded) existential rules with default negation and analyze conjunctive query answering complexity under well-founded and stable model semantics. Provide data and combined complexity bounds for the well-founded case but prove stable models incompatible due to stickiness enabling cartesian-product encodings.
