feat(codex): add DeepSeek native Responses support with official catalog mirror

- Switch the DeepSeek preset to openai_responses and align context
  windows with the official catalog (1048576)
- Mirror DeepSeek's official models.json verbatim for native /responses
  providers on deepseek.com hosts, keeping the official GPT-5 harness
  and freeform apply_patch registration self-consistent
- Make catalog spec displayName/contextWindow explicit-only (Option) so
  local defaults no longer clobber official vendor values
