claude-code keeps its MCP servers in state, not events (novox/hq ADR 0202)

One key per registration in the module's servers bucket — all.<server> or
<node>.<server> — watched by every node, so a node assigned after a
registration takes it at start, which the mcp.registered event could not do.
Also narrows apply()'s refusal by hand: the builder compiles without strict,
where the discriminated union does not narrow and the build failed.
