Adds the three release-prep artefacts so the repo is ready for
the chain store: Apache-2.0 LICENSE (boilerplate), NOTICE with
per-module copyright + third-party + methodological lineage
attribution, and the compiled wasm32-wasip2 release bundle
(module.wasm) that the Hub will install verbatim once published.
Cargo.lock is now also tracked so reproducible builds line up
with the WASM hash that ships.
