The public leaderboard now scores adoption from real consumers

The public Elo Index leaderboard ranks pricing functions on adoption, confidence, speed and cost efficiency. Adoption previously had nothing behind it: every listing reported the same unmeasured value, and the leaderboard scored every function's adoption identically regardless of how often it was actually used.

Adoption now counts the distinct consumer workspaces that call each function. A provider's calls to its own function, demo traffic, pay-per-call traffic and sandbox workspaces do not count, so the number reflects real consumers rather than volume anyone can generate. A function nobody has adopted scores 0.

To protect individual customers, a function's usage numbers are published only once at least three distinct consumers use it. Below that, total_invocations and the new distinct_consumers are null and stats.usage_status reads below_threshold. Confidence still has nothing behind it and stays unmeasured for now, so data_status on each entry reads partial rather than measured. The scoring method is now version 3.
