Pass `--competitors` on a single-entity topic and the engine auto-discovers
2-6 peer entities via web search, runs the full pipeline on each in
parallel, and returns one N-way comparison reusing the existing 9-axis
Head-to-Head scaffold. `last30days OpenAI --competitors` resolves to
Anthropic + xAI + Google Gemini; `last30days Kanye West --competitors`
resolves to Drake + Kendrick Lamar + one more peer.
- New CLI flags: --competitors, --competitors=N, --competitors-list
- New scripts/lib/competitors.py — mirrors resolve.auto_resolve pattern
(web search + deterministic text extraction, no internal LLM)
- New scripts/lib/fanout.py — ThreadPoolExecutor orchestrator; per-entity
failures degrade gracefully as long as >=2 entities survive
- Multi-report render in scripts/lib/render.py reuses the comparison
scaffold for the synthesis table
- LAW 7-style stderr when no backend and no list, pointing the hosting
reasoning model at --competitors-list
- 38 new tests across CLI parsing, discovery, fanout, and rendering
