No almacene errores de Graph API de forma indefinida.

La condición !r.ok incluye respuestas temporales como 429 y 5xx. igNameCache guarda "", y las llamadas posteriores retornan ese valor sin otra solicitud mientras viva el isolate. No almacene respuestas no exitosas o use una entrada negativa con expiración corta.

In `@src/channels/meta.ts` at line 128, No almacenes valores negativos en

especialmente para errores temporales 429 o 5xx. Ajusta el flujo asociado a

Add focused tests for Instagram profile enrichment. The current tests cover only parseMetaEvents. They do not send a signed POST /webhooks/meta through the enrichment branch, so a regression in metaProfileName, the displayName assignment, or the ordering before ingest would pass. Add route-level coverage for successful "Nombre · @usuario" formatting, cache reuse, and Graph failures that still call ingest without a display name.

In `@src/index.ts` around lines 134 - 138, Add route-level tests for signed POST
/webhooks/meta requests that exercise the Instagram enrichment branch in the
webhook handler: verify successful metaProfileName enrichment produces “Nombre ·
`@usuario`” before ingest, repeated requests reuse the cache, and Graph failures
still call ingest without a displayName. Keep existing parseMetaEvents tests
intact and use the project’s established signing and mocking helpers.
