zuraffa_agent_platform_interface

Method-channel implementation of the zuraffa_agent AgentPlatform seam (spec 115): bridges the federated platform packages (zuraffa_agent_android, zuraffa_agent_ios, zuraffa_agent_macos) to the shared channel contract.

Host apps normally depend on the app-facing zuraffa_agent package and register the federated adapter for their platform — this package is the shared implementation those adapters ship through.
