/**
|
|
* chatCore Claude system-role lifter (Quality Gate v2 / Fase 9 — chatCore god-file
|
|
* decomposition, #3501).
|
|
*
|
|
* Pure helper extracted from chatCore.ts: lifts any `system`/`developer` role messages out of the
|
|
* messages[] array into the top-level `system` field. Anthropic's Messages API rejects either as a
|
|
* chat role, so they must be hoisted. `developer` is OpenAI's Responses-API rename of `system` and
|
|
* is treated identically. Mutates the payload in place; behaviour is byte-identical to the previous
|
|
* top-level definition (still re-exported from chatCore.ts for existing importers/tests).
