Register `CN` for Caplin, Erigon's embedded consensus layer client. Caplin integrates the consensus layer directly into the Erigon node, removing the need for a separate CL process and its own disk storage, which reduces operational complexity and resource usage. It is a distinct consensus client and needs its own two-letter code so that blocks proposed by an Erigon + Caplin setup are correctly attributable. `EG` is already reserved for erigon (execution layer), so it cannot be reused for the consensus layer: the graffiti client-version format (`<EL code><EL commit><CL code><CL commit>`) requires distinct codes to tell the two layers apart. With `CN`, an Erigon + Caplin block encodes as e.g. `EGa53eCNa53e`, letting client-diversity tooling measure Caplin adoption independently.
