`_resolve_typescript_member_calls` resolves a member call's receiver to a type
definition by casefolded label. For a builtin-typed receiver (`x: Date;
x.getTime()`), `_key("Date")` == "date" matched a same-named user `class DATE` /
`const DATE` in another file, binding the caller to it as a phantom
`references[call]` edge. In a real 3,368-file repo one module-local `const DATE`
accumulated 469 false cross-file edges (degree 472, betweenness 0.435) — a false
god node distorting path/god-node results.
Skip the resolution when the receiver type is an ECMAScript/Python builtin
global (Date, Promise, Map, ...), mirroring the guard the cross-file CALL
resolver already applies (#726). The guard is a strict no-op for genuine user
types, so legitimate constructor-injection member-call resolution (#1316) is
unaffected. Verified across new Date().method(), return-type, and var-decl-type
shapes: zero phantom edges, user DATE degree back to 1.
