initguru f3acf4f811 fix(sse): inject global system prompt once, post-translation, across all target shapes (#12904)
* fix(sse): inject global system prompt post-translation for codex/Responses path

codex/Responses requests carry input[]+instructions, not messages[]. The
existing injectSystemPrompt runs PRE-translation (chatCore.ts) and only
handles messages[]/system fields, so the Global System Prompt (After Prompt =
suffixPrompt) never reached the provider for codex — verified 0/84 call logs
while the catalog base_instructions reached 84/84.

Add injectSystemPromptPostTranslation() and call it after prepareUpstreamBody
on the resolved messages[]. With multiple system/developer messages (codex
normalises its per-item developer roles to system), prefix goes on the FIRST
and suffix on the LAST so the After Prompt retains the highest recency
position — the semantics injectSystemPrompt's single-findIndex buries.

Also wire OMNIROUTE_SYSTEM_INSTRUCTION_APPEND on the /v1/messages (Claude
Messages -> OpenAI Chat Completions) translation path. The directive was
previously only wired on the Responses API path, so DeepSeek-V4 kept leaking
English planning/chain-of-thought into the content field on Claude Code
sessions that route through /v1/messages. Mirror the openai-responses.ts
pattern: append to string system, append a text block for array content, or
unshift a new system message when none exists.

Tests: 23/23 (19 system-prompt incl. 6 postTranslation + codex regression;
4 claude-to-openai directive append). typecheck:core clean.

* test(sse): reproduce global prompt double injection — single-injection contract tests

* fix(sse): unify global prompt injection to single post-translation pass

* fix(sse): carry single global-prompt injection across claude/gemini/responses target shapes

* fix(sse): restore global-prompt coverage for carrier-less targets via gated pre-translation pass

* fix(sse): cover codex/gemini source shapes in the carrier-less pre-translation gate

* fix(types): preserve generic system prompt return

* fix(sse): correct file reference in claude-to-openai.ts comment and add changelog fragment

Points the #reasoning-bilingual comment at the real companion file
(translator/response/openai-to-claude.ts's directivePreambleStripper.ts
from #12905) instead of the nonexistent "openai-responses.ts", and adds
the changelog fragment referenced in the PR body but missing from the
diff.
