Adds fakeecosystem_test.go: a shared fakeServer wrapping httptest.Server with request capture, a runtime-toggleable fault (SetFault) that makes a running fake Nexus/Praxis/Hexis fail closed like a real outage without tearing the server down, protocol fixtures for each service's documented response shapes, and a settable fakeClock for time-dependent assertions. Uses it in ecosystem_harness_test.go to cover a gap the existing ad-hoc per-test httptest servers didn't reach — handlePraxisAct had zero test coverage — plus a fault-then-recovery test showing the same fake flapping mid-session, the shape the earlier fail-closed fixes (#272/#273) need regression coverage against.
