* fix(systemstatsmonitor): key disk_percent_used by device_name only
disk_percent_used declared only device_name but recorded four labels
(device_name, fs_type, mount_option, state). With per-metric label
validation, Record now rejects the undeclared labels and the metric is
dropped from the export (caught by the metriconly e2e).
Record only device_name, preserving the schema NPD has exported since the
metric was introduced: the OpenCensus view aggregated by device_name and
dropped the other tags, so on the wire this metric has always had a single
label. It also maps to the Google-owned
compute.googleapis.com/guest/disk/percent_used descriptor, which can reject
writes carrying undeclared label keys. Add a regression test pinning the
schema.
* fix(prometheus): preserve legacy metric names

* fix(stackdriver): skip descriptor management
* chore(deps): update module metadata
* fix(metrics): align fake label handling
* fix(metrics): reject normalized name collisions
* fix(stackdriver): preserve custom metric names
* fix(stackdriver): use portable metric paths
* fix(otel): shut down meter provider on exit and reject late registrations
Address review comments from #1297:
- Shut down the OTel meter provider when npdMain exits so push readers
flush pending metrics.
- Return an error from AddMetricReader/AddResourceAttributes when the
meter provider is already initialized, instead of silently ignoring
the registration.
* chore(deps): tidy go.sum after rebase
* chore(deps): remove OTel migration scaffold
* refactor(metrics): consolidate metric mappings
