`ninja plugin publish --bnp <file>` uploads a .bnp built by `ninja plugin
build` instead of a source archive. The orchestrator verifies the .bnp
layout/ABI/name/version server-side and records its abi_version. Without
--bnp, publish keeps shipping a source archive for backwards compatibility
until the CMS install path is wasm-native.
