Improve search indexing and reduce news subscription usage

[svg8bit]

Summary

• split Google News sitemaps by locale and bounded parts, add localized canonical/hreflang metadata, structured data, crawlable archives, IndexNow deltas and WebSub notifications
• keep the main map UI unchanged while canonicalizing legacy/preview routes
• request a complete ten-story edition in one bounded research call, cap top-up rounds at three, and shrink the repeated exclusion payload without weakening deterministic novelty checks
• back off hard subscription-limit probes from 6 to 12 to 24 hours while preserving the staged edition and keeping ordinary quality/source retries at 30 minutes

Verification

• npm run check
• npm run test:e2e (144 passed)
• targeted news tests (24 passed)
• live production endpoint audit before release confirmed the current empty /news-sitemap.xml and missing split child route
