0.52.0 (2026-06-15)

⚠ BREAKING CHANGES

• ModelLoadCoordinator.dispatchLoad(_:) gains a defaulted drivesChatSeams: parameter (source-compatible; allowlisted in the API-break gate). Binding-based consumers that hand-mirrored ChatViewModel.selectedModel into ModelRegistry.selectedModel to work around feat: add ModelRegistry.selectModel(_:) selection hook point #1312 can drop that mirroring: selection now clears the mutually-exclusive endpoint synchronously.
