Kinda.CallError exception (kinda v0.12.0)

The exception raised when a generated NIF call fails.

Native wrappers populate stable diagnostic fields in addition to the legacy :message. Generated public wrappers enrich argument failures with names, declared C types and the category of the original Elixir value.

KINDA_DUMP_STACK_TRACE=1 prints a native error return trace for internal native failures. Input decoding errors do not suggest a native trace because the caller already has enough information to correct the invocation.
