Session C (night2): the aggregator mounted — Explore hub, lens panels, one filter

- StreaksPanel renders THE LENS (interpreted read + tonight difficulty) +
  snapshot grade letters; streaks are FREE for every tier per the product
  definition (the picture is free, the read is paid) — only hot lists keep
  the free top-3 gate.
- One stat selection now filters ALL layers: card props narrow together
  with streaks + hot lists (Slate activeStat → slateGameToCardData).
- /explore = server SEO shell (daily-indexable: 'MLB Hit Streaks, Hot
  Hitters & Stat Leaders') + ExploreHub client: leaders + full streaks +
  hot lists, real-tier gated, defaults to the in-season sport.
- Landing teaser fixed: it pointed at NBA (off-season → self-hid forever);
  now MLB top-3 through the lens — the anonymous-visitor hook actually
  shows.
- Player dossier: ACTIVE STREAKS block (free, lens reads) via new
  ?player= filter on /api/streaks/:sport.
- Schedule layer already the Slate base (mergeSlate) — verified, no change.
