Module artifacts 

Host-side artifact discovery, freshness, and Wasm build helpers.

These functions keep integration-test artifacts in caller-selected target directories and contain no application-specific package or profile policy. Independent Wasm batches remain sequential; WasmBuildSession adds only explicit cross-call resolution reuse under a caller-held source lease.
