Add a Grafana dashboard for the four KMS backend operation metrics
emitted at the policy choke point, Prometheus alert rules with
conservative default thresholds (pending staging baseline calibration),
and an operations runbook documenting the metric contract and the
response procedure for each alert. Register the new alert rules file in
the observability READMEs.
Refs rustfs/backlog#1584 (part of rustfs/backlog#1562)
The GET body cache exports 11 `rustfs_object_data_cache_*` metrics but no
bundled dashboard visualized them. This adds one so operators can see the
cache's behaviour without hand-writing PromQL.
New `grafana-object-data-cache.json` (auto-provisioned from the dashboards
directory, `${DS_PROMETHEUS}`, schema 38) with 19 panels covering every metric:
hit ratio and lookup outcomes, plan decisions and cacheable ratio, fill
outcomes and fill-duration quantiles, hit-vs-fill byte throughput, entries and
weighted bytes vs capacity, in-flight fills, memory-pressure skips,
invalidations by reason/outcome, and size-class breakdowns. PromQL matches each
metric's type — rate() for counters, histogram_quantile() for the fill-duration
histogram, direct reads for gauges.
The observability README (EN + ZH) dashboard table gains a matching row.

* chore(ci): upgrade protoc from 30.2 to 31.1
- Update protoc version in GitHub Actions setup workflow
- Use arduino/setup-protoc@v3 to install the latest protoc version
- Ensure compatibility with current project requirements
- Improve proto file compilation performance and stability
This upgrade aligns our development environment with the latest protobuf standards.
* modify package version
* refactor(deps): centralize crate versions in root Cargo.toml
- Move all dependency versions to workspace.dependencies section
- Standardize AWS SDK and related crates versions
- Update tokio, bytes, and futures crates to latest stable versions
- Ensure consistent version use across all workspace members
- Implement workspace inheritance for common dependencies
This change simplifies dependency management and ensures version consistency across the project.
