Detailed Description

Thin facade over eso::uatools::Client, exposing the legacy IComm-shaped OPC UA client API.

Throws std::runtime_error on failure, so callers can keep their existing try { ... } catch (...) { CCFTHROW(...) } idiom unchanged.

The VectorVariant/Variant types in the signatures are the CCF value containers (ifw::core::protocol::base); they are pure data types and carry no OPC UA transport — the transport is entirely ualib.
