fix(desktop): stop artifact over-indexing

Require explicit provenance for tool-result artifacts while preserving assistant links, MEDIA deliveries, generated outputs, file mutations, and browser screenshots. Normalize persisted Unix-second timestamps at collection time and retain millisecond fallbacks.

Consolidates current-main-compatible work from #41156 and #48577.
