Now mutations snapshot will be built

Official CH changelog text
Now mutations snapshot will be built from the visible parts snapshot. Also mutation counters used in snapshot will be recalculated from the included mutations. #82945 (Mikhail Artemenko).
Mutations snapshot generation now uses the visible parts snapshot as its basis, with mutation counters recalculated from the included mutations.

Why it matters

This change ensures that mutations snapshots accurately reflect the current visible state of the data parts, improving consistency and correctness when working with mutations in ClickHouse.

How to use it

Users can benefit from this feature transparently as the mutation snapshots and counters are recalculated automatically during snapshot generation without requiring any manual configuration.
