Integrate discussion #4 status corrections and references

Apply 264 record-specific reviews from discussion #4 and all four follow-ups, with source references, explicit preprint qualifications, partial-progress scope, and research-programme tags. Confirm 90 Erdős resolutions and retain nine disputed entries as open. Reconcile legacy status fields with the dated literature reviews; refresh the dataset card and counts. Preserve all 15,458 statements and historical research reports.

+### Status corrections — 2026-09-27
+
+Integrated [discussion #4](https://huggingface.co/datasets/ulamai/UnsolvedMath/discussions/4) and its four follow-ups:
+264 record-specific reviews, including 90 source-confirmed Erdős resolutions,
+the Kourovka updates, references for independent write-ups, and qualified partial results.
+The nine disputed Erdős entries remain open according to the maintained source.
+Ambiguous problem numbers are matched by integer record ID. Research programmes are tagged
+`research-programme`; `status` retains its existing three-value schema.
+
+`status` is now consistent with the dated literature review and the website.
+`status_review` records the correction provenance, kind and evidence level;
+`literature_assessment`, `literature_sources` and `literature_checked_at` carry its explanation
+and references. “Solved” includes refutations and independence results, and some resolutions
+are explicitly unrefereed claims. Reconciled August triage claims have not been independently
+proved by this update. The original AMR/AIM research reports and classifications are historical.
