v4.6.2

Fixed

• Corrected stale PRICING for models the drift watch (#44) flagged — kie's advertised rates had moved well past our table:
  • happyhorse/* (1.0 T2V/I2V/R2V/Video Edit): 8/10 cr/s (a competitive-positioning guess) → 48 cr/s (kie published 28 @720p, 48 @1080p — the entries' default). These were never officially priced before.
  • wan/2-5-text-to-video / -image-to-video: 3 → 12 cr/s (kie published 12 @720p default, 20 @1080p); added to PRICING_ESTIMATED.
  • grok-imagine/upscale: 5 → 10 cr (flat, kie published).
• Refreshed the now-false "8 cr/s estimate" claims in the HappyHorse 1.0 costEfficiency research notes to the real published rates. (Verdicts/comparisons still carry their lastResearched: 2026-05-05 date — a full re-research is a separate task.)

All three clear the drift watch after the fix; the runtime [actual] cost from #42 remains ground truth regardless.
