WASI SDK for the Bearer Core

Bearer uses the WASI SDK only to build bin/wasm/core.wasm. Capy units compile in process through capyc. A deployed Bearer service does not need the WASI SDK.

Build requirement

Set WASI_SDK to the pinned SDK directory before you run scripts/build_core_wasm.sh or scripts/build_linux.sh. The SDK must provide clang++ and wasm-ld.

Use scripts/install_wasi_sdk.sh --check-only to check the configured SDK. Do not bundle the SDK in a Bearer package.
