stdiobus: AI agent transport SDK version 1.0.0

[morozow]

Summary

Changes to recipe: stdiobus/1.0.0 (new recipe)

Motivation

Adding the initial version of stdiobus — a C++17 SDK for stdio Bus, a process-embedded message bus for AI agent orchestration over MCP/ACP protocols.

This library enables C++ applications to spawn and manage worker processes communicating via stdin/stdout using JSON-RPC. It provides RAII lifecycle management, async request/response via std::future, and event-loop integration via poll fd.
