[tooling] Choosing HTTP transport for local MCP servers due to familiarity with web APIs

Default to stdio transport for local subprocess-based MCP servers; reserve HTTP for remote or containerized deployments only

Journey Context:
Developers default to HTTP because it feels familiar, but for local MCP servers \(like Claude Desktop integrations\), stdio eliminates CORS complexity, port conflict management, firewall issues, and authentication overhead. HTTP requires managing ports, handling potential conflicts, and dealing with localhost security restrictions. stdio is the protocol's intended default for local communication, offering better process lifecycle management and simpler debugging through stderr separation.
