news_transformer: clamp ORT threads, disable intra-op spinning; spec marked implemented in ForexBot2

Same two load_model lines as the copy vendored into ForexBot2/news_model.py
(2026-09-27), so the files stay identical on the scoring functions.

 # Specification: run the ML-NEWS XAU transformer inside ForexBot2
 
-Status: **specification only, not implemented.** Written 2026-09-27 so a coding agent can implement it
-later without this conversation. Every file:line reference was checked against the repos on that date;
-re-verify before editing, the numbers drift.
+Status: **IMPLEMENTED 2026-09-27** (ForexBot2 branch `sql-integration`, on top of `6af1237`; suite
+Module 38). The text below is the specification as written before the implementation; file:line
+numbers refer to `6af1237` and have drifted. Where the implementation differs, this list wins:
+
+- **`primary` mode does not archive the cycle's rows.** Owner decision during implementation: once the
+  local model scores, `logs/newsdata.db` stops growing, because the model's own output is not training
+  data. Only the DeepSeek audit copies (`deepseek_audit_per_day`, shipped 0) are written. `off` and
+  `fallback` archive as before (a `fallback` model row carries `model_teacher`). §5.4 and §9 read
+  accordingly.
+- `_audit_with_deepseek` **returns** the `llm` copies; there is no `_pending_audit_rows` attribute.
+  The mode switch of §5.2 lives in `NewsEngine._enrich_headline_scores(scored, mode)`, which returns
+  those copies, so the call site and the tests share one function.
+- `config.json.example` ships `"mode": "off"`; the live server sets `primary`
+  (`deploy/README-news-model.md`).
+- §8 step 0 was wrong: the dashboard daemon never writes the archive in any mode
+  (`set_db_writes_for_process(False)`), so its DeepSeek rows are not "free audit labels". Both
+  processes load the model (owner decision); `NEWS_MODEL_MODE=off` stays as the memory fallback.
+- `warm_up_in_background()` is implemented (module-level once flag; a `NewsEngine` is built per scan).
+- `news_model.get_news_model()` also treats a missing `path` as a load failure (one warning).
+- `requirements.txt` floors: `onnxruntime>=1.30,<2`, `tokenizers>=0.23.2,<1` (the versions that
+  verified the bundle).
+- ML-NEWS `news_transformer.py` received the §3.4 edits in the same session; the vendored copy differs
+  only in `load_model` having no default directory.
