Mechanical platform-floor bump to iOS 17 / macOS 14 / visionOS 1 (tvOS still excluded) so KadrPhotos can depend on Kadr ≥ 0.15.0. Part of the coordinated ecosystem iOS 17 move. Dropped 8 redundant @available annotations; refreshed stale docstrings referencing Kadr's removed speed(_:)/speed(curve:) overloads (docs only — no code called them). No behavior change. Consumers needing the iOS 16 floor stay on 0.6.x. 80 tests pass.
