V8003 abi_version_mismatch
The WASM module was compiled against a runtime ABI this host does not implement (runtime/rt/ABI.md §0): its major version differs, or its minor version is newer than the host's, so it may need imports the host lacks.
An error from the package phase. sakura explain V8003 prints this explanation offline.
The WASM module was compiled against a runtime ABI this host does not implement
(runtime/rt/ABI.md §0): its major version differs, or its minor version is newer than the
host's, so it may need imports the host lacks. Rebuild the module with this compiler, whose
backend, runtime and host share one ABI revision.

V8002 reserved_package_name
sakura.toml names its package std or main (design §9, §17.131).
V8004 target_unsupported_external
A user package declares an @external(js, …) function, and --target wasm has no JavaScript to call (design §17.81): the WASM backend runs std's host operations through the runtime's own imports only.
