What changed

Package change

API pricing simplified by removing volume-based tiered pricing [Opus 4.6: flat $5/MTok input (was $5 for ≤200K, $10 for >200K tokens), $25/MTok output (was $25 for ≤200K, $37.50 for >200K); Sonnet 4.6: flat $3/MTok input (was $3 for ≤200K, $6 for >200K), $15/MTok output (was $15 for ≤200K, $22.50 for >200K); all prompt caching simplified to single rates; Haiku 4.5 unchanged]
