Input SystemFix
Fix single clicks generating duplicated touch events, when using Device Simulator and Touch Simulation. When the Device Simulator view is enabled Touch Simulation events are supressed.
Fixed a NullReferenceException when reopening a device's Device Debug View window in the Input Debugger after it had previously been maximized and closed.
Fixed an Input Actions importer error message that incorrectly reported a duplicate Action Map name when the actual problem was a duplicate Action name within an Action Map.

Fixed devices that were disconnected or reconfigured while the application was out of focus staying in the device list.
Fixed issue on macOS where third party tools sending repeated key down events without a key up could result in keys becoming stuck
Fixed polling for interaction phases (such as WasPerformedThisFrame) being missed during Update due to interaction timeouts sometimes occurring during the later before-render period when a before-render device (such as an XR HMD) is added. This means that timeouts and interactions like Hold may now wait to perform until the next frame instead of the earliest chance during before-render.
Fixed the "Location Distance Threshold" label being clipped and misaligned on the Input System Settings project settings page.
Fixed the Input Actions editor window being recreated (flickering) when cancelling the unsaved-changes prompt on close; the window now uses the Editor's standard unsaved-changes handling.

Repeat test-player builds no longer assign a fresh GUID to the PerformanceTestRunInfo.json/PerformanceTestRunSettings.json assets on every build. Previously, deleting these assets' .meta files as part of post-build cleanup caused Unity to assign a new GUID on the next build, which the data pipeline treated as a change and triggered a full asset rebuild even when nothing else changed. The .meta files are now cached in Library/ between builds and restored before the assets are rewritten, scoped to builds with test assemblies.
