fix(rendering): reconcile shadow roots from live runtime

Browse source 
Recover ordinary live roots from LiveEntityRuntime's canonical active spatial workset instead of relying on already-retained derived records. Keep attached children callback-authoritative, cache immutable selection geometry fingerprints, and pin zero-allocation retained update paths with regression tests.

Release gate: 3,733 App tests / 3 skips; 8,217 complete-solution tests / 5 skips.
