C4: cross-process HTTPS content parity (C# transfer service, TS provider, TS reader)

Browse source 
The TS provider runs in its own process on node:https with the fixture credential. The TS reader and the C# transfer service over the unmodified HTTPS connector (CustomRootTrust, fixture certificate only) each fetch from it; the orchestrator judges URL parity, the empty chunk, corrupt-store faults and the untrusted control. test:interop is wired in cultmesh-browser and the workflow, and the cultmesh-ts step now precedes the browser step.
