/**
* #10967: format an `exhaustedConnections` key stored by targetExhaustion.ts
* (`markAuthLevelExhaustion` / `markAgentrouterConnectionQuotaExhaustion` /
* `markConnectionLevelExhaustion`, all keyed as `` `${provider}:${connectionId}` ``)
* into a diagnostics `excluded` entry.
*
* Before this fix, `buildComboDiag` (combo.ts) hardcoded `provider: "unknown"` and
* `slice(0, 8)`'d the WHOLE key — for a typical `jina-ai:<uuid>` key that produced
* `exhausted_connection:jina-ai:` (the 7-char provider id + colon consumed the
* entire 8-char budget, the UUID silently dropped, and the real provider id
* discarded in favor of the literal string "unknown").
*
* Splitting on the FIRST `:` recovers the real provider id and truncates only the
* connection-id half (never the full UUID, matching the public combo projection's
* connection-id redaction policy — #2300).
