[real-value/wallet] add pilot proof command

[FlowmemoryAI]

Summary

Closes #136.

• Adds the root npm run flowchain:real-value-pilot:wallet command and wires it to the wallet/operator pilot E2E proof.
• Adds wallet/operator pilot schemas, public envelope validation, signing/verification CLI paths, PowerShell helper wrappers, and operator docs for the capped owner pilot.
• Updates the real-value pilot matrix to current main at c4959f8, marking the control-dashboard proof as merged and the wallet proof as branch-local pending this PR.
