Report #85118

[tooling] MCP server works locally but fails when containerized or deployed serverless

Switch from stdio to HTTP with SSE transport for containerized deployments, or ensure the container allocates a TTY and handles SIGTERM properly for stdio

Journey Context:
Stdio transport requires a persistent parent-child process relationship and breaks when containers isolate stdout/stderr or when running in serverless environments that expect HTTP. HTTP/SSE transport allows stateless horizontal scaling, health checks, and load balancing. While Claude Desktop uses stdio for local processes, production agents talking to containerized MCP servers must use HTTP to avoid zombie processes and broken pipe errors.
