Golden Boot race from structured ESPN scoring plays

ESPN's keyEvents carry participants[].athlete for goals — no text
parsing needed. The normalizer now extracts scorer/scoring/shootout
(payload versioned, with a boot backfill that re-stores summaries
saved by the old normalizer), /api/goldenboot aggregates per-player
goals (own goals and shootout kicks excluded), and the Teams page
leads with the top-10 race. Verified against tonight's real goals.
