fix(extraction): never fabricate an edge from a call-result receiver (#1748)

A member call whose receiver is itself a call — `d.setdefault(k, []).append(v)`,
`make().run()` — used to drop the receiver at extraction time, degrade to the
bare method name, and exact-match any top-level project symbol of that name
(Python and JavaScript/TypeScript). Keep the inner callee encoded as
`<inner>().<method>` in the TS extractor and native kernel; the name-matcher
refuses to guess for that shape (store-accessor exception only). Based on
#1692, rebased onto main after #1746. Fixes #1683.
