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

Browse Source 
- 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

/**
* Deep Research — standalone end-to-end test harness
*
* Imports the extension's REAL source (fresh, uncached) and runs the full
* research pipeline with real Firecrawl + real pi agent sessions.
*
* WHY: pi caches extension modules per session (keyed by path + cwd +
* generation) and only invalidates on /reload or cwd change. Tool calls in
* a live session therefore run the version loaded at session start. This
* harness bypasses that cache so you can iterate on src/ without reloading
* pi, and it prints verification stats (round stats, angle provenance,
* corroboration distribution, citation integrity, authority stats).
*
* Usage (from repo root):
* NODE_PATH=/opt/homebrew/lib/node_modules bun scripts/run-harness.ts \
* "<question>" [depth] [breadth] [audience]
*
* Requires the pi SDK to be resolvable (NODE_PATH above points at the
* global pi install) and Firecrawl reachable (settings.json firecrawl.baseUrl).
* Report is written to /tmp/deepi-harness/report.md.
