…rged #38 (#41) Re-applies the 6 blocking clinical-safety fixes (B1-B6) on top of current main. PR #38 merged 22 RAG fixes before these blockers landed, and #39/#40 did not address them, so main still trusts wrong doses. - B1: numeric verification now matches by exact normalized token-set membership instead of substring, so "2.5 mg" no longer verifies against "12.5 mg" (5x dose error). Fails closed. - B2: fold unicode superscripts (×10⁹/L) to ASCII before extraction/match. - B3: percentage branch no longer ends in \b (which could never match), so percentages extract and percentage mismatches are flagged. - B4: numeric gate now scans answerSections[].body (medication_dose), scoped to each section's citation_chunk_ids. - B5: safeFallbackAnswer fails closed on parse failure (ungrounded, no citation back-fill) and still runs the numeric gate; extractive recovery and strong-retry routing updated accordingly. - B6: retry route reset is a single conditional UPDATE guarded on status/locked_at; 0 rows affected => 409, closing the TOCTOU race. - N1: verifyAnswerNumbers fails closed when no cited chunk maps to a result.

This PR implements logical improvements to the RAG pipeline, including LLM query re-writing, semantic chunking, and boilerplate suppression.
