Pull request overview

Adds support for non-local remote transports by introducing a new “plain C++” TCP/TLS transport stack (Boost.Asio-based) with explicit transport configuration and wiring it into the existing Logos transport factory and API surface.

Changes:

• Introduces plain wire protocol primitives (messages, framing, JSON/CBOR codecs) and a TCP/TLS RPC runtime (client/server, connection management).
• Extends SDK API to support explicit per-instance / per-client transport configuration (including multi-transport publishing on the provider side).
• Adds unit tests for framing and codecs, and updates build + Nix/flake dependencies to include Boost/OpenSSL/nlohmann_json.

callMethodAsync() can invoke the callback synchronously when the connection is closed (callback(QVariant())), but LogosObject explicitly requires callbacks be delivered on a subsequent event-loop iteration. Please defer this callback (e.g., via a queued invocation/timer) to match the interface contract.
