No breaking changes. The only diff is the following PR: - #525 - This PR updates the engine reload() and unload() methods to allow users to abort an uncompleted reload() by either: - call unload() any time before reload() completed - call reload() again before the previous reload() completed - Besides, it fixes the previous issue where `device lost error` is raised unexpectedly when user simply switches a model ### TVMjs - To support the above PR, TVMjs is updated and compiled at apache/tvm@1fcb620 - Difference: - Device error lost fix: apache/tvm#17250 - Add AbortSignal to fetching APIs: - apache/tvm#17208 - apache/tvm#17227 - apache/tvm#17233

This PR fixes an issue introduced in #17005.
deviceLostIsErrorwas introduced to make sure intentionaldispose()(hence webgpu'sdestroy()) does not cause device lost callback to treat it as an error. However, we cannot setdeviceLostIsErrorimmediately to true after callingthis.lib.dispose()(which callsdevice.destroy()) because WebGPU is asynchronous. Otherwise, we would trigger the device lost callback when callingInstance.dispose()to destroy device intentionally.
