Each banner was re-verified against the current binary (repro now behaves
correctly) and cites the actual fix location in current src/** plus the covering
regression example. Closes the stale-but-fixed backlog: 0019, 0042-0056, 0131.

# issue-0043: lazy-lowered function bodies don't resolve runtime-class method dispatch
> **RESOLVED.** Root cause: chained runtime-class dispatch (`Cls.alloc().init...(x)`) collapsed the inner call's return type, so the outer `.method(...)` couldn't find the receiver's `#objc_class` declaration — and on the lazy-lower path (inside an `inline if OS == .ios` branch) the runtime-class map was unavailable.
> Fix: the runtime-class instance/static dispatch now resolves each call's declared return type via `resolveRuntimeMethodReturnType` against the runtime_class_map (`src/ir/calls.zig`, runtime-class branches ~L244-269 / L385-398), and that map lives on the shared `ProgramIndex` (`src/ir/program_index.zig:668`) so it is equally visible to eager and lazy lowering (`lazyLowerFunction`, `src/ir/lower/decl.zig:2508`).
> Covering regression: `examples/1306-ffi-objc-runtime-class-chained-dispatch.sx` (header cites issue 0043) exercises both `*ClassName` and `*Self` chained shapes and passes.
**FIXED.** The original repro
(`sx build --target ios-sim issue-0043.sx` with a
`UIWindow.alloc().initWithWindowScene(scene)` call inside an
