Agent Skills: moon-relay-kernel

Explicit-only entrypoint for Moon Relay Kernel task routing and adaptive workflow execution. Use only when the user explicitly names `moon-relay-kernel`, invokes `$moon-relay-kernel`, or explicitly asks to use the Kernel skill or Kernel mode for the current task. Do not infer activation from installed availability, AGENTS.md, track markers, repository context, or a task that merely concerns Kernel.
