First incremental variable on the path back to Oboe integration. Changes
are deliberately minimal: add cc = "1" to [build-dependencies] (cargo
build-deps resolve against the host so the line is unconditional), and
on the Android target run a single cc::Build step that compiles
cpp/hello.c — a 6-line file that defines one function (`wzp_hello_stub`)
that is never called from Rust.
Goal: verify that merely introducing a C static library into the .so
via cc::Build does not regress the working build (#17, commit 5309938
= build #6 behaviour: launches, renders home screen, registers on
relay). If this build still works, we know cc::Build pipelines alone
are fine and can move to the next variable.
