Ignacio Pastor 05d1ca549b fix(codex): rescue reasoning-only turns that die with 'remained incomplete after 3 continuation attempts'
grok-4.x on the xAI /v1/responses surface sometimes ends a turn with only
reasoning items — no message output item, no tool calls — and those
reasoning items carry no encrypted_content. Two compounding problems:

1. The model occasionally emits its final answer INSIDE the reasoning
   channel, delimited by grok's internal "<response>" tag. The answer
   exists but is classified reasoning-only → finish_reason=incomplete.

2. An interim assistant message holding only plain-text reasoning replays
   as nothing in _chat_messages_to_responses_input, so every continuation
   request is byte-identical to the one that just failed. The model
   deterministically repeats the reasoning-only response until the retry
   budget is exhausted and the turn dies with "Codex response remained
   incomplete after 3 continuation attempts".

Fixes:
- _normalize_codex_response (xai_responses only): salvage the
  <response>-delimited tail from the reasoning text and promote it to
  assistant content; the untagged prefix stays as thinking text.
- Codex-incomplete continuation path: when the interim message has
  nothing the input converter will replay (no content, no encrypted
  reasoning items, no message items), append a user-role nudge so the
  retry actually differs and explicitly asks for the final answer /
  pending tool call. Mirrors the existing _get_continuation_prompt
  pattern used for length truncation.

Observed live with grok-4.20 on xai-oauth (2026-07-13); sibling of the
grok-composer web_search incomplete-loop fix in transports/codex.py.
