Function extract_java_method_reference

internal/cbm/extract_calls.c:1846–1867

Java method reference `Lhs::name` (e.g. `String::length`, `Foo::new`). The call walk only visits call_expression-like nodes, so a method_reference never becomes a call and the LSP's lsp_method_ref resolution has no call site to attach to. Record a textual call to the referenced method's bare name (the constructor ref `Lhs::new` uses the unnamed `new` token); the LSP join then matches on the bare n

// matches on the bare name. The referenced method IS invoked indirectly, so
// this is an accurate call edge (mirrors java_lsp.c resolve_method_reference).
