Find Unused Metrics in VictoriaMetrics

Identify metrics that are being ingested but never (or rarely) queried, then recommend concrete actions to stop wasting storage and ingestion resources.

Environment

Uses the same env vars as the victoriametrics-query skill:

# $VM_METRICS_URL - base URL
#   cluster: export VM_METRICS_URL="https://vmselect.example.com/select/0/prometheus"
#   single: export VM_METRICS_URL="http://localhost:8428"
# $VM_CURL_CONFIG - curl config file with auth header (unset if no auth is required)
#   Remote: export VM_CURL_CONFIG="$HOME/.config/victoriametrics/curl.conf"
#   Local:  leave unset (defaults to /dev/null - no auth)
