Add 4 independent seed brands: Latham, Stine, 1st Choice, Burrus (+623 varieties)

Browse Source 
Four independent regional brands across IA/IN/IL (variety-identity sources,
each parsed into structured characteristics_groups so ratings embed):

- latham (264: 155 corn + 109 soy) — Latham Hi-Tech Seeds, Alexander IA.
  WordPress REST enum (/wp-json/wp/v2/varieties) + /products/<slug>/ detail
  HTML. Scale 1-9 LOWER=better (reversed, like NK/AgriPro).
- stine (217: 58 corn + 159 soy) — Stine Seed, Adel IA (largest US
  independent). sitemap enum + /{crop}/traits/<slug>/<code>/ detail HTML.
  Corn 1-9 (9=best); soy qualitative.
- first_choice (78: 52 corn + 22 soy + 4 wheat) — 1st Choice Seeds,
  Rushville IN (employee-owned). Per-crop sitemap -> detail HTML. Scale
  0-10 higher=better. ~40 older corn pages thin at source; wheat
  identity-only.
- burrus (64: 38 corn + 26 soy) — Burrus Seed, Arenzville IL. Seedware
  JSON API. Scale 1-10 (10=best). Brands Burrus/Power Plus/DONMARIO.
  robots ai-train=no + named-bot blocks; operator opted in, scraper uses a
  non-blacklisted UA + honors Crawl-delay 10.

All 623 validated through rag.chunk.chunks_from_variety (0 errors; 6
identity-only pages from source gaps). No chunk.py change needed (identity
sources auto-route to chunks_from_variety).

Docs:
- sources.json: 4 entries + Hoegemeyer added to _excluded_sources. The
  Corteva ToU (shared across pioneer.com / hoegemeyer.com / therightseed.com
  / corteva.com + the Vylor spinoff) bans scrapers + competitive use, so the
  whole Corteva family is one excluded ToU domain.
- docs_mcp/lessons.md: rating-scales updated with all 4 directions +
  an explicit cross-vendor warning (Latham 1=best vs Stine/Burrus higher=best
  — never compare raw numbers without _scale_direction).
- README + CLAUDE corpus inventory: now 2,268 variety + 6,787 trial records.

CI rebuilds the index from the committed corpus.

### Not in the corpus (documented in `docs_mcp/lessons.md`)
- **Pioneer / Corteva** — ToS bans automation. Curated fallback lesson points the farmer at pioneer.com / a local dealer.
- **Pioneer / Corteva (all brands)** — ToS bans automation. This now covers the whole Corteva family — Pioneer, Brevant, **Hoegemeyer** (the consolidation brand absorbing Seed Consultants / Dairyland / Nu-Tech / Terral), and the upcoming Vylor spinoff — all share the same corteva.com ToU. Curated fallback lesson points the farmer at a local dealer; legitimate Corteva-data paths are an official license (openinnovation@corteva.com) or university-extension trial data.
- **NK yield-results** — fiddly ASMX/SOAP endpoint, needs a dedicated reverse-engineer session.
- **Bayer per-variety trial data** — not publicly indexed (DEKALB / Asgrow trial data flows through Channel reps). Partially covered by the GH plot reports' cross-vendor results.
