Two bugs in generate-news-enhanced.ts identified by code review.

Changes

• Remove search_anforanden from week-ahead sources — generateWeekAhead() never calls client.searchSpeeches(), so the source was a false declaration. Removed to keep declared MCP tools in sync with actual calls.

• Guard against empty topSlug — Titles composed entirely of non-ASCII characters (e.g. Swedish Å/Ä/Ö) produce an empty string after the ASCII-only sanitization regex, which would propagate an invalid slug into breaking-news generation. Added || 'news' fallback:

// Before — empty string possible for non-ASCII titles
const topSlug = topDoc
  ? ((topDoc['titel'] || 'news')
      .toLowerCase()
      .replace(/[^a-z0-9\s-]/g, '')  // strips all Å/Ä/Ö → ""
      .replace(/\s+/g, '-')
      .slice(0, 40))
  : 'news';

// After — IIFE with explicit fallback
const topSlug = topDoc
  ? (() => {
      const cleaned = (topDoc['titel'] || 'news')
        .toLowerCase()
        .replace(/[^a-z0-9\s-]/g, '')
        .replace(/\s+/g, '-')
        .slice(0, 40);
      return cleaned || 'news';
    })()
  : 'news';
