Fix occlusion capture failure sticking native surface and tab close leaving recording stuck
Bug 1: When captureSurfaceFrame rejects, the error was swallowed and occlusionCaptureRequestedRef remained true, preventing retries and leaving the native surface visible above the overlay. Now on capture failure, the ref is reset to allow retries, and setSurface is called with false to hide the native view so overlays remain interactive. Bug 2: When HostedBrowserWebview unmounts, the lease cleanup released the desktop tab (clearing recordingTabIdRef on main process) but nothing stopped the renderer-side recording. The module-level active variable stayed set, causing subsequent startBrowserRecording calls to fail with BrowserRecordingConflictError. Now stopBrowserRecording is called on unmount before releasing the lease.

Fix occlusion capture failure sticking native surface and tab close leaving recording stuck
Bug 1: When captureSurfaceFrame rejects, the error was swallowed and
occlusionCaptureRequestedRef remained true, preventing retries and leaving
the native surface visible above the overlay. Now on capture failure, the
ref is reset to allow retries, and setSurface is called with false to hide
the native view so overlays remain interactive.
Bug 2: When HostedBrowserWebview unmounts, the lease cleanup released the
desktop tab (clearing recordingTabIdRef on main process) but nothing
stopped the renderer-side recording. The module-level active variable
stayed set, causing subsequent startBrowserRecording calls to fail with
BrowserRecordingConflictError. Now stopBrowserRecording is called on
unmount before releasing the lease.
