OpenRouter Efficiency Updates, Multi-contract dApps in QuickDApp

From agent-ready to agent-in-the-loop

Made Tempo Zone return types portable across declaration-emitting projects.

Fixed isHash returning true for odd-length hex strings. size rounds odd-length hex up to the next whole byte, so a 63-character hex string reported a size of 32 and passed the check. isHash now valid…
