Review Comment:
The calculateChainSize method traverses the entire snapshot chain without
cycle detection. In the case of corrupted data or circular references, this
could lead to infinite loops. Consider adding a maximum depth limit or cycle
detection mechanism.

Review Comment:
The conversion factor (1024.0 * 1024.0 * 1024.0) is duplicated from the
physicalsize and virtualsize formatting above. Consider extracting this magic
number into a constant or utility function to improve maintainability.

Review Comment:
[nitpick] The default value for snapshotShowChainSize is set to "true",
which could impact performance for systems with deep snapshot chains. Consider
defaulting to "false" to be conservative and require explicit opt-in for this
potentially expensive feature.

ConfigKey<Boolean> snapshotShowChainSize = new
ConfigKey<>(Boolean.class, "snapshot.show.chain.size", "Snapshots", "false",

Review Comment:
This version change from "4.21.0.0-SNAPSHOT" to "4.21.0.0" appears unrelated
to the snapshot chain size feature and should likely be in a separate commit or
PR focused on release preparation.
