Ping QiuandClaude Opus 4.6 a9a5e455c6 fix: Lookup/ListAll return copies, add UpdateEntry for safe mutation 
Lookup() and ListAll() now return value copies (not pointers to
internal registry state). Callers can no longer mutate registry
entries without holding a lock.

Added clone() on BlockVolumeEntry with deep-copied Replicas slice.
Added UpdateEntry(name, func(*BlockVolumeEntry)) for locked mutation.
ListByServer() also returns copies.

Migrated 1 production mutation (ReplicaPlacement + Preset in create
handler) and ~20 test mutations to use UpdateEntry.

5 new copy-correctness tests: Lookup returns copy, Replicas slice
isolated, ListAll returns copies, UpdateEntry mutates, UpdateEntry
not-found error.

Ping QiuandClaude Opus 4.6 bb691a5458 feat: CP11B-4 observability pack — health state, alerts, dashboard 
Health-state derivation: deriveHealthStateWithLiveness() computes
per-volume state (unsafe > rebuilding > degraded > healthy) using
role, replica count, durability mode, degraded flag, and primary
server liveness. Used consistently in both volume responses and
cluster summary.

Extended GET /block/status with health counts (healthy, degraded,
rebuilding, unsafe) and NVMe-capable server count. Response is now
typed BlockStatusResponse instead of untyped map.

Default alert pack: 7 Prometheus rules covering WAL pressure,
flusher errors, replica degradation, rebuilding, scrub errors.
Alert rules reference real seaweedfs_blockvol_* metric names.

Default dashboard: Grafana JSON with 17 panels — cluster health,
IOPS, latency P99, WAL pressure, flusher throughput, replication,
scrub, dirty map, epoch.

17 tests: 9 health derivation, 1 cluster summary, 2 handler/API,
2 alert validation, 2 dashboard validation, 1 liveness parity.

Ping QiuandClaude Opus 4.6 683969086c feat: CP11B-1 provisioning presets + review fixes 
Preset system: ResolvePolicy resolves named presets (database, general,
throughput) with per-field overrides into concrete volume parameters.
Create path now uses resolved policy instead of ad-hoc validation.
New /block/volume/resolve diagnostic endpoint for dry-run resolution.

Review fix 1 (MED): HasNVMeCapableServer now derives NVMe capability
from server-level heartbeat attribute (block_nvme_addr proto field)
instead of scanning volume entries. Fixes false "no NVMe" warning on
fresh clusters with NVMe-capable servers but no volumes yet.

Review fix 2 (LOW): /block/volume/resolve no longer proxied to leader —
read-only diagnostic endpoint can be served by any master.

Engine fix: ReadLBA retry loop closes stale dirty-map race when WAL
entry is recycled between lookup and read.
