[real-value/runtime] add pilot proof command

[FlowmemoryAI]

Closes #134.

Summary

• Adds the root flowchain:real-value-pilot:runtime command.
• Adds deterministic runtime support for bridge asset/account mappings, bridge credits, bridge credit receipts, replay index, and Base event receipt index.
• Adds bridge-handoff and bridge-receipt CLI flows plus restart/export/import coverage for bridge-specific roots.
• Adds infra/scripts/flowchain-real-value-pilot-runtime.ps1, which consumes the bridge proof output handoff with source chain 8453 when present and falls back to the committed local fixture for standalone runtime development.
• Updates local runtime docs and the HQ pilot matrix for issue [real-value/runtime] Add pilot runtime proof command #134.

Scope

Worktree: E:\FlowMemory\flowmemory-live-wallet
Branch: agent/real-value-pilot-runtime-proof

Runtime proof scope touched crates/flowmemory-devnet/, devnet/, infra/scripts/, package.json, and docs/. It did not touch contracts, bridge relayer source, dashboard source, crypto wallet internals, services implementation, or hardware.

Validation

• cargo test --manifest-path crates/flowmemory-devnet/Cargo.toml - passed, 35 integration tests.
• cargo fmt --manifest-path crates/flowmemory-devnet/Cargo.toml --check - passed.
• [scriptblock]::Create((Get-Content -Raw infra/scripts/flowchain-real-value-pilot-runtime.ps1)) | Out-Null - passed.
• powershell -NoProfile -ExecutionPolicy Bypass -File infra/scripts/flowchain-real-value-pilot-runtime.ps1 -RunDir . - expected failure; refused to clear the repository root.
• npm run flowchain:real-value-pilot:runtime - passed; runtime report showed handoffSource: bridge-proof-output and source chain 8453 when the bridge output existed.
• npm run flowchain:real-value-pilot:e2e - passed; this includes npm run flowchain:product-e2e, npm run flowchain:l1-e2e, contracts, bridge, runtime, wallet, control-dashboard, and ops proof commands. Final report had missingProofs: 0.
• node infra/scripts/check-unsafe-claims.mjs - passed.
• git diff --check - passed with Git line-ending warnings only.

Current Blockers

None on this branch. main remains blocked for the final strict pilot gate until this runtime proof PR merges.

Boundary

This is local/testnet runtime proof work for a capped owner pilot. It does not add custody, withdrawal release guarantees, production bridge security, tokenomics, public validator readiness, public L1/mainnet readiness, or production deployment behavior.
