* feat(filer): record object size distribution histogram Add SeaweedFS_filer_object_size_bytes, a histogram sampled when an object is first created in the filer namespace, covering every write protocol (S3, WebDAV, FUSE mount, direct HTTP). Buckets follow the 1KB/100KB/1MB/100MB/1GB ranges operators use to size collections. Directories, overwrites, and metadata-only updates are not sampled, so the bucket counts track the size distribution of distinct objects. * feat(metrics): add filer object size distribution dashboard panels Add a write-rate-by-size-range graph and a size-distribution bar gauge, driven by SeaweedFS_filer_object_size_bytes, to the standalone and Helm Grafana dashboards. Per-range subtractions are clamped at zero so transient negative rate() samples do not render below the axis.
