Four new InputAction entries for held-key offset integration (CameraZoomIn/Out, CameraRaise/Lower; default unbound). Six new DebugVM mirror properties forwarding to CameraDiagnostics so the upcoming "Chase camera" DebugPanel section can drive them live. Also folds in four small cleanups from the Task 4 code review: - Both CameraDiagnostics-mutating tests in CameraControllerTests now use try/finally save/restore (consistency with Task-3 follow-up B) - Drop unused `using System.Numerics` from CameraControllerTests - Reword the XML doc on CameraController.Active to explain WHY both cameras are held simultaneously (flag flip takes effect on the next Active access without re-entry) rather than restating the getter logic Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
