release: v1.5.1 — zwasm pin v2.2.1 -> v2.3.0 (engine follow)

zwasm v2.3.0 = the WASI-0.3.0-official inventory-sweep release (docs
truth-sweep + wasi:clocks/system-clock host support + Homebrew
packaging). No embedding-API / behaviour / JIT-output change; cljw
-Dwasm build + phase16 wasm e2e (ffi / run / engine_select) verified
green on the new pin. Version 1.5.0 -> 1.5.1 (patch: dependency follow).
