Next-depth pass: network-stack, CRDTs, gossip, scheduling, experimental

Expand introspection helpers and getStats(protocol) across six categories
after the storage/trust giant pass.

network-stack (10): listPeerIds, hasPeer, bestPeer, listCircuitIds,
queueDepth, listPendingIds, and related helpers; protocol in getStats.

state-crdts: crdt-map has/size/entries; conflict-set size/isEmpty;
reactive-state size/keys; richer getStats on map and conflict-set.

messaging-gossip: gossip-mesh seenCount/clearSeen; dedup size/clear;
event-bus getStats merges metrics/topics/peers.

scheduling-queues: topic-lease listShards/isHeld; peer-scheduler listJobs;
activity-queue pending/claimed stats.

measurement-rate-control: bucket-rate listPeerIds/peerCount.

experimental (16): protocol-rich getStats; mycelium listPeerIds/totalCredits;
pheromone listPathIds.

Docs: API Methods for link-probe, crdt-map, gossip-mesh; expanded category
READMEs for state-crdts, messaging-gossip, scheduling, measurement.
