0.2.0: per-query analysis, cross-query corroboration, expanded authority scoring

- Per-query result grouping: findings analyzed under the query that produced
  them, with angle + query provenance carried through to synthesis
- Cross-query corroboration via multi-query URL counts (before global dedup);
  same-query findings no longer corroborate each other
- Robust LLM JSON parsing (code fences, trailing commas, prose prefixes)
- Expanded domain authority map to 90+ domains + LOW_AUTHORITY_DOMAINS floor;
  authority-aware source truncation in analysis prompts
- Citation integrity: authoritative bibliography replaces LLM references,
  hallucinated inline citations stripped
- Near-duplicate title detection for syndicated articles; cross-round finding
  dedup with quality-ranked 30-finding synthesis cap
- Junk result filtering, retry-with-backoff, fixed successfulSearches count
- Standalone harness (scripts/run-harness.ts) for cache-bypassing iteration
