feat(go-services): tracker share_* handlers (complete ingest) + shadow tuning

Browse source 
- share.go: cross-machine vital sharing (share_subscribe/unsubscribe/share_*),
  faithful port of the peer-state snapshot + plugin fan-out + /vital-sharing/peers.
  The last ingest handler — the Go tracker now handles every plugin event type.
- shadow consumer: drop the outbound keepalive ping (the firehose is never idle)
  and tighten the read-deadline watchdog to 12s for faster reconnect after the
  upstream's periodic eviction (full-firehose browser clients get evicted ~every
  90s; the watchdog recovers it, ~90% duty cycle). Production-bound /ws/position
  is unaffected (plugins connect to us; no eviction).
