fix(anthropic): scope api default normalization

 ### Fixes
 
 - Exec/YOLO: stop rejecting gateway-host exec in `security=full` plus `ask=off` mode via the Python/Node script preflight hardening path, so promptless YOLO exec once again runs direct interpreter stdin and heredoc forms such as `node <<'NODE' ... NODE`.
+- Anthropic/plugins: scope Anthropic `api: "anthropic-messages"` defaulting to Anthropic-owned providers, so `openai-codex` and other providers without an explicit `api` no longer get rewritten to the wrong transport. Fixes #64534.
 - fix(qqbot): add SSRF guard to direct-upload URL paths in uploadC2CMedia and uploadGroupMedia [AI-assisted]. (#69595) Thanks @pgondhi987.
 - fix(gateway): enforce allowRequestSessionKey gate on template-rendered mapping sessionKeys. (#69381) Thanks @pgondhi987.
 - Webchat/images: treat inline image attachments as media for empty-turn gating while still ignoring metadata-only blank turns. (#69474) Thanks @Jaswir.
