Description

This PR tightens the call-resolution core in the registry to prevent false-positive CALLS edge resolutions when dealing with qualified receivers, improving precision across all supported languages.

Changes

• Restricted resolve_same_module on receivers: The resolve_same_module strategy now validates the receiver prefix. It will correctly resolve self-receivers (self.get), exact module prefixes (proj.pkg.service.get), and last-segment namespace matches (service.get). It actively rejects resolving to local functions when the receiver is clearly unrelated (e.g., axios.get or _get_store().get), preventing spurious edges to same-named functions within the current module.
• Restricted resolve_name_lookup for qualified callees: Added a qn_ends_with_qualified check. If a callee name is explicitly qualified (e.g., contains . or ::), the resolution candidate's qualified name must properly terminate with that exact qualification (unless the candidate is explicitly labeled as a Method), preventing cross-namespace leakage on generic method names.

Impact

• Precision vs Recall: This change heavily favors precision, eliminating wide blast-radius false positives on common method names (like get, add, update) when invoked on unrelated imported or delegated receiver objects.
• Testing: Added regression tests for resolve_same_module_only_on_self_receiver and verified the full test suite runs cleanly.
