Johnathan Corgan c77e564462 control: serve high-traffic show_* queries off the rx_loop hot path ...

Introduce a read-snapshot plane so pure-snapshot control queries render in
the control-socket task instead of round-tripping the rx_loop, removing the
head-of-line coupling that let a busy or slow rx_loop time out fipsctl and
fipstop observability.

- ControlReadHandle: a cloneable bundle the control accept loop holds, over
  the node's already-shared NodeContext and MetricsRegistry plus an
  ArcSwap-published StatsSnapshot. A snapshot_dispatch seam serves cut-over
  commands off-loop and falls through to the rx_loop for the rest, keeping
  the rx_loop's ownership of Node intact.
- StatsSnapshot is published from the tick (the natural and sole mutator of
  stats_history), carrying the history rings plus the scalar gauges and
  counts show_status reports. Readers serve the latest snapshot
  unconditionally, with staleness bounded by the tick interval and no
  IO_TIMEOUT-coupled fallback.
- Off-loop now: show_status, show_stats_history, show_stats_all_history,
  show_listening_sockets, show_stats_list, and a new counter-only
  show_metrics (exposed as fipsctl "stats metrics", the enabler for a
  Prometheus scraper at no hot-path cost). Queries that need live per-entity
  state (peers, links, sessions, routing, and the per-peer stats variants)
  stay on the rx_loop path pending later phases.

Quartet green; forward-merge to next verified clean.
