[frontier] Monolithic agent architectures blocking independent scaling deployment and language heterogeneity

Decompose agents into MCP-capable microservices where each sub-agent exposes capabilities via the Model Context Protocol server interface, enabling language-agnostic composition and independent horizontal scaling.

Journey Context:
Early multi-agent systems built monolithic Python apps with hardcoded agent classes importing each other. This couples deployment \(can't scale the 'code reviewer' agent separately from 'planner'\) and forces language uniformity \(all Python\). The 2025 pattern is treating each specialized agent as an MCP Server implementing the Model Context Protocol, exposing tools/resources via stdio or HTTP SSE. The 'supervisor' agent is an MCP Client that connects to these servers. This allows the 'code review agent' to be written in Rust for speed, the 'planner' in Python, deployed as separate Kubernetes pods, and scaled independently based on load.
