/**
 * OpenKernel — Agent Backend registry + built-in CLI specs
 *
 * Holds the executors a node can route a task to. 'kernel' (the native path) is
 * always present and handled inline by the Federation manager; the CLI backends
 * are advertised only when their binary is actually installed, so the mesh's
 * compute-router won't send a `claude` task to a node without Claude Code.
 *
 * Each CLI is invoked in headless / non-interactive mode. Flags are the stable
 * public ones for each tool; a device can override the binary or append args via
 * env (INFINICODE_<CLI>_BIN / INFINICODE_<CLI>_ARGS) without a code change.
