docker: production image + Gitea Actions for monthly refresh

Dockerfile: self-contained image with corpus + Chroma + BM25 baked
in. Drawbar's compose pulls + runs without volume mounts. Built from
sources.json (labels schema), PRODUCT_NAME=crop_chem by default,
HYBRID_SEARCH=true (always-on for production quality). RERANK_URL +
OLLAMA_URL get set at compose time.

.gitea/workflows/refresh.yml: monthly cron (1st @ 06:00 UTC) does
full scrape → reindex → image push. Scrapes Bayer (~30 min) +
EPA PPLS row-crop filtered (~7h). Skips reindex+push if no corpus
diff. Tags pushed: :latest, :<sha12>, :corpus-<YYYY.MM.DD>.

.gitea/workflows/image-only.yml: on-demand or auto on code-only
pushes to main (paths: docs_mcp/, rag/, scrape/, requirements.txt,
Dockerfile, sources.json). Reindexes from committed corpus, builds
image, pushes. ~10 min vs ~9h full refresh.

.gitignore: corpus/ now COMMITTED (4,159 labels, 265 MB of .md +
sidecars). Lets image-only.yml rebuild indexes without re-scraping.
chroma/ + bm25/ still gitignored (regenerable binary indexes).

.dockerignore: drops venv, eval results, PLAN/README/CLAUDE.md,
deploy/, .git/ — keeps the image lean. corpus + chroma + bm25
explicitly NOT in dockerignore (those go INTO the image).

+DO NOT impregnate SQUADRON onto coated am­
+monium nitrate or limestone because these materials 
+will not absorb the herbicide. Dry fertilizer blends 
+containing mixtures of ammonium nitrate or limestone 
+may be impregnated with SQUADRON. A mini­
+mum of 200 pounds of impregnated dry bulk fenil­
+izer. excluding the weight of ammonium nitrate or 
+limestone. must be applied per acre. 
+Apply SQUADRON atthe rate of3 pints per acre. 
+Use the table on page 2 to determine the amount of 
+SQUADRON to be impregnated on a ton of dry 
+bulk fertilizer based on the rate of fertilizer which 
+will be applied per acre.

+Apply the SQUADRON/dry bulk fertilizer mixture with an accurately calibrated dry fer.i1izer spreader. 
+The SQUADRON/dry bulk fertilizer mixture must be spread uniformly on the soil surface. Uneven
