8-step NDJSON-streaming pipeline that compares two Barnevernet documents:
classifies each doc, extracts parties and timelines, cross-references both
for contradictions/deletions/additions, retrieves corpus legal context, and
synthesises a full discrepancy report with tabbed UI.
New files: DiscrepancyAgent.php, api/discrepancy.php, discrepancy.php,
discrepancy.js. Modified: FreeTier.php (cost=4), i18n.php (all 4 langs),
tool-svgs.php (DC icon), tools.css (dc-* component styles).
