// Canonical mothership OTel metric names. Call sites should reference
// `Metric.<Identifier>` (e.g. `Metric.CopilotToolDuration`) rather than raw
// string literals, so the Go-side contract is the single source of truth and
// typos become compile errors.
//
// NAMES ONLY. Label keys and histogram bucket boundaries are NOT in this
// contract — Go owns the label-cardinality allowlist and the shared bucket
// constant, and the Sim emitter MUST mirror those by hand so the Go∪Sim metric
// union is queryable as one series set.
