Every generated library exports both ABIs side by side; spell out the choice in
the example READMEs: the native (pure-C) ABI is the default for same-process /
local calls (flat C structs, zero serialization), while the CBOR ABI exists
solely for inter-process communication (different process or machine). In a
shared address space CBOR is pure overhead, so prefer native locally.
