ApplyHook
ApplyHook dispatches a caller-supplied callback on gImm. The callback's parameter type is /r/launderrvictim-declared, so /p/ packages can't supply this hook — only /r/ realms can.
Command
gnokey query vm/qeval -remote "https://rpc.gno-staging.moul.p2p.team" -data "gno.land/r/tests/vm/launderrvictim.ApplyHook()"
