Add meta data to contract WASM on build

To build a smart contract, use the stellar contract build command. The --meta option will allow you to add additional meta data entries to the contractmetav0 custom section of the resulting WASM file at build time.

cookbooktest.ignore

export SHA=$(git rev-parse HEAD)

stellar contract build \
    --manifest-path ./cmd/crates/soroban-test/tests/fixtures/test-wasms/hello_world/Cargo.toml \
    --meta source_repo=https://github.com/stellar/stellar-cli \
    --meta commit_sha=$SHA

You can then use stellar contract info meta to see the meta data:

stellar contract info meta \
  --wasm target/wasm32v1-none/release/test_hello_world.wasm
