VictoriaMetrics Cardinality Analysis

Systematic cardinality analysis for VictoriaMetrics. Collects TSDB status, metric usage stats, and label value patterns, then produces a structured report with specific relabeling and stream aggregation configs the user can apply directly.

The goal is to find the highest-impact optimization opportunities — metrics nobody queries, labels that explode cardinality for no monitoring value, and patterns that indicate data hygiene problems (error messages as labels, SQL text as labels, UUIDs as labels).
