// Engine capabilities / features (handler.h #77-#84, #87-#89). Each callback
// returns true when the engine overrides the capability (value written through
// the out-pointer) and false to fall back to the handler base default. Enums
// (row_type, ha_key_alg) cross as their raw int value; HA_CREATE_INFO is an
// opaque `const void *`. explain_extra assigns into the shim-owned std::string
// via mysql__std_string__assign (defined in handler_caps.cc).
