# claudemesh runner — executes deployed MCP servers as child processes.
# Multi-runtime: Node 22 + Python 3.12 + uv + Bun
#
# The runner supervisor (Node) listens on HTTP :7901 for commands from
# the broker (load, call, unload, health, list_tools). Each deployed
# MCP server runs as a child process with its own stdio pipe.
