fix: Exclude streamTimestamp from Metafile equivalence check

IvanPartsunev · IvanPartsunev · commit 1a77eefed620 · 2026-01-26T21:59:35.000+02:00
streamTimestamp is a system property set at commit time, so it should
be excluded from equivalence comparisons (like IDs and other locators).
This fixes test_recursive_cross_catalog_copy failing because copied
deltas have different timestamps than originals.
