Zhengchao An d31bd3cd10 fix(data-usage): make thin usage-cache types a read-only projection (#5981)
Delete the dead ecstore save_data_usage_cache and the thin
DataUsageCache::marshal_msg it was the only caller of, drop the
Serialize derive (and the dead DataUsageCacheStorage trait with its
save path) from the thin projection types so no write path can exist
outside the scanner's canonical map-encoded writer, and pin the
persisted .usage-cache.bin wire bytes with cross-crate fixture tests
on both the scanner writer and the thin reader.

RustFS Scanner

RustFS Scanner is the background maintenance scan loop. It handles usage accounting, lifecycle expiry and transition admission, bucket replication repair admission, scanner-driven heal/bitrot checks, and namespace alerts.

For operator-facing runtime controls, status fields, and tuning workflows, see Scanner Runtime Controls. For repeatable scanner-pressure validation, see Scanner Benchmark Runbook.

Chinese documentation is available in README.zh-CN.md.
