Define SLI metrics across Mimir subsystems: write path (distributor), ingester/TSDB/shipper, query frontend, querier, store gateway, HTTP/gRPC API, compactor, ruler, ring, KV store, and query engine. Metrics sourced from a running Mimir instance and upstream Mimir dashboards/alerts.
Add compactor, dispatcher, lifecycler, metastore, MetaStore, nflog, preloading, ruler, shipper, silences, storegateway, StoreGateway, and TSDB to the custom wordlist for the Alertmanager, Loki, and Mimir SLI documentation.

Summary
Define Service Level Indicator (SLI) metrics for Mimir, following the same structure as the existing Tempo, Grafana, Prometheus, Alertmanager, and Loki SLI documents. Metrics were sourced from a running Mimir instance and the upstream Mimir dashboards and alerting rules were reviewed for recommended SLI patterns (request error/latency alerts, ingester series limits, store gateway preloading efficiency, etc.).
