fix(core): guard PhysicsSystem against unregistered Grabbed component.

zjm-meta · meta-codesync[bot] · commit 7c1ba031eb64 · 2026-05-26T16:44:57.000-07:00
Summary: T270858631 called out a bug that Physics System checks Grabbed component during its runtime which caused unnecessary bundling with the Grabbing System. This diff fixed the issue by checking if the Grabbed component is registered before checking its value.
