diegosouzapw c14e43a52f fix(translator): preserve body.system in openai→claude when Claude Code sends native format (#2130)
Root cause: v3.7.9 fix for #1966 removed the unconditional CLAUDE_SYSTEM_PROMPT
injection, which also removed the else branch that always set result.system.
When Claude Code sends system prompt as body.system (native Anthropic array)
through /v1/chat/completions, the translator only looked at role='system'
messages in body.messages — body.system was silently dropped.

Fix: The translator now checks for body.system and preserves it:
- If both body.system and role='system' messages exist, they are merged
- If only body.system exists, it passes through as-is
- If only role='system' messages exist, behavior unchanged
- If neither exists, result.system remains undefined (no forced injection)

Also removes the dead CLAUDE_SYSTEM_PROMPT import.

Includes 4 regression tests covering all combinations.
