Kristoffer Dalby 7706552c99 state: gate reconnect PolicyChange on NodeNeedsPeerRecompute ...

Connect and Disconnect appended change.PolicyChange() on every reconnect. PolicyChange sets RequiresRuntimePeerComputation, so the batcher rebuilt a full netmap (packet filters, SSH policy, peer serialization) for every connected node — O(N) per reconnect, O(N^2) on a restart storm. On a small VM this saturated CPU after the v0.28 -> v0.29 upgrade.

Emit it only when the node's online state changes what peers compute: subnet routers, relay targets, and via targets. An ordinary reconnect now sends just the lightweight online/offline peer patch. Relay and via targets still recompute, so peers drop a stale PeerRelay allocation when a relay goes offline.

Fixes #3293
