Extends engram_act_stats_json with five monotonic counters for the raw incoming
signals the mind receives — aff_activations (spreading activations run),
aff_queries (activate_json entries), aff_node_creates, aff_ise_ingests (ISE
nodes), aff_edge_creates. Module-scope statics incremented at the entry points,
emitted via the existing act-stats mechanism and rotated with it — MEASURED, and
never accreted as memory nodes. Process-lifetime totals, reset on restart like
the other _eg_act_* gauges. Additive JSON fields (backward-compatible); no graph
behavior changes. act-stats buffer grown 896->1088 to hold them.
MEASURED on a copy: after 5 node creates (2 ISE), 2 edge creates, then 4+3
queries — counters read exactly node_creates=5, ise_ingests=2, edge_creates=2,
queries=activations=4 then 7; create counters unchanged by queries; queries
strictly monotonic across readings. ASan+UBSan clean.
