The exporter ingests the feed's ImportedBlock (code 6) reports and keeps,
per block hash, the first reporter and its lead over the second. Each tip
block is joined with that after 8 s; a reward preimage gets the node's
telemetry name once at least 3 of its blocks were attempted and 60% or more
were first reported by the same node. Emitted as
quantus_author_node_info{preimage,display,node_name,peer_id,self} confidence
with attempts/attributed counters per preimage; display is the name, or
the abbreviated preimage (first 8, last 4) when no confident attribution.
Measured today: leads are 40-100 ms for authors on the feed (the network is
better connected than when 200-700 ms was measured), so the lead threshold
is 20 ms and identity consistency carries the attribution. Validated for
ten minutes against bob: ours -> baba-gorchitsa, 0x2ccf39 -> quanpool-planck,
GUI miners -> QuantusMinerGUI at confidence 1.0.
Dashboard: the leaderboard joins quantus_author_node_info and shows the
display label as "author" in place of the reward preimage; the "ours" column
is gone, so the panel is fit to share. ARENA_DEBUG=1 turns on debug logging
(per-block attribution decisions).
Closes#11.
