Reactor step: triggers ONE real wasm4pm-ex4pm-bindings algorithm against
the shared Wasmex instance Ex4pmEngine.Reactors.WasmCapabilitiesReactor.BootWasm
booted, via the real Ex4pmEngine.Wasm.RealTransport.default_transport/2
-- no fixture closure, real WASM execution and real replay verification on
every invocation.
Arguments: :algo -- one entry from Ex4pmEngine.Wasm.RealTransport.algo_specs/0,
passed as a literal Reactor value/1 argument (fixed per step at DSL
compile time, one :run_<algo> step per registry entry).
Always returns {:ok, %{standing:, ...}}, never {:error, _} -- a real
execution failure for THIS algorithm is reported as a :blocked/
:unsupported standing in the returned map, not as a step failure, so one
algorithm's real defect never aborts the other 18 independent steps or
triggers Reactor's own undo/compensate machinery for work that has
nothing to compensate (every algorithm here is read-only: authority: :construct_only, actuation_performed: false, per
Ex4pmEngine.Wasm.Adapter.accept/4's own evidence map).
