openfut-bridge: add openfut-poke gate-forcer + xref tooling

openfut-poke: live /proc/mem inspector and go-online gate-forcer for FIFA 23,
built during the forcing arc (resolves connMgr, reads/forces the online
decision). xref.rs: PE string-literal cross-reference finder used to locate
the redirector-dial / online-environment sites. Wire openfut-poke into
[[bin]].
