Even though the cluster metadata partition contains a feature level record
for kraft.version:
```
bin/kafka-dump-log.sh --files
/tmp/kraft-combined-logs/__cluster_metadata-0/00000000000000000000.log
--cluster-metadata-decoder | grep "kraft.version" | grep "FEATURE_LEVEL_RECORD"
| offset: 540 CreateTime: 1741886527606 keySize: -1 valueSize: 20 sequence:
-1 headerKeys: [] payload:
{"type":"FEATURE_LEVEL_RECORD","version":0,"data":{"name":"kraft.version","featureLevel":1}}
```
The controller's ApiVersions reports the correct kraft.version:
```
bin/kafka-features.sh --bootstrap-controller localhost:9093 describe
Feature: eligible.leader.replicas.version SupportedMinVersion: 0
SupportedMaxVersion: 1 FinalizedVersionLevel: 0 Epoch: 4579
Feature: group.version SupportedMinVersion: 0 SupportedMaxVersion: 1

```
The broker's ApiVersion reports the correct finalized kraft.version:
```
bin/kafka-features.sh --bootstrap-server localhost:9092 describe
