Needle Engine

• AR starts more reliably from iOS App Clips, and switching scenes keeps the camera view visible.
• Short Timeline audio clips now use their intended volume immediately when playback starts.
• Closing scenes releases resources more reliably, helping long sessions use less memory.
• Physics shapes stay aligned with rotated or scaled objects.
• Environment previews display correctly after reloads, and background blur responds as expected.
• Material and visibility fixes improve how models render.
• Model exports and production builds work with more project setups.
• Gizmo labels can stay visible in front of scene objects when needed.

Unity Integration

• Added a setting to manage web project package versions yourself.
• Needle's custom editor links now work across multiple Unity Inspector windows.
• Improved compatibility with newer Unity 6 releases.

• Add: Unity project setting to manage web project package versions manually while keeping local npmdef paths valid.
• Fix: Ignore reflection probes on unlit materials.
• Fix: Apply Timeline audio volume before short clips start playing.
• Fix: Register the App Clip AR session listener before the asynchronous support check, so the first session grant is not missed on slower pages.
