Lib.rs

Cross-repo qname-match resolver.

Walks every registered repo in the registry, collects each repo's (name, node_id) pairs, then for each Calls edge whose dst is a bare name (not an existing local node id), looks up matching symbols in other repos and writes a CROSS_CALLS edge into the registry DB.

This is a deliberately narrow MVP — name-only matching, no overload disambiguation, no module-prefix awareness. Confidence is fixed at 0.4 to reflect that.
