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).

+DIRECTIONS FOR USE 
+It is a violation of Federal law to use this product in a 
+manner inconsistent with its labeling. The use of 
+STEEL' herbicide not consistent with this labeling may 
+result in injury to crops. DO NOT apply this product 
+through any type of irrigation system. 
+This label must be in the possession of the user at the 
+time of herbicide application. 
+GENERAL INFORMATION 
+STEEL' provides control of many broad leaf and grass 
+weeds when applied preplant or preemergence. 
+STEEL' may be applied in the late fall for control of 
+weeds in no-till or conventional soybeans. rather than in 
+the spring prior to planting. Treated areas should be 
+planted to ROUNDUP' READY soybeans in the 
+following spring. and. if required. ROUNDUP' ULTRA 
+applied in-season in a planned sequential program. 
+USE RATE 
+Apply STEEL' at the rate of 3 pints per acre. If heavy 
+grass or waterhemp pressure is expected. add 
+PROWL' 3.3 EC herbicide to the spray mixture at a rate 
+of up to 1.25 pints per acre. 
+Apply ROUNDUP' ULTRA at 1 to 1.5 pints per acre. 
+APPLICATION INFORMATION 
+Apply STEEL' after October 31. and prior to ground 
+freeze-up in the winter. Fall and winter precipitation will 
+activate the herbicide for control of most winter annual 
+weeds and spring germinating weeds in no-till and 
+conventional soybeans. 
+ROUNDUP' READY soybeans should be planted in the 
+spring following the fall application of STEEL'. If weeds 
+emerge in-season. ROUNDUP' ULTRA may be applied 
+postemergence for weed control. 
+For fall applications in no-till systems. ensure that fields 
+are weed free prior to application. If not. apply a 
+burndown application of GRAMOXONE'M EXTRA. 
+TOUCHDOWN". or ROUNDUP' ULTRA to control 
+existing weeds. 
+Refer to the STEEL' product label for additional 
+information on application instructions. 
+NOTIFICATION 
+JUN 1 4 2002
+
+USE AREA 
+Fall applications of STEEL may be made only in the 
+states of Delaware, Illinois, Indiana, Iowa, Kansas, 
+Kentucky, Maryland, Michigan, Minnesota (south of 
+state highway 210), Missouri, Nebraska, Ohio, 
+Pennsylvania, Virginia, West Virginia and Wisconsin. 
+ROTATIONAL CROP INFORMATION 
+Refer to rotational crop restrictions listed in the 
+STEEL" herbicide product label. 
+NOTE: For fall applications of STEEL", adjust the 
+rotational crop intervals by basing the interval on the 
+date of soybean planting rather than the date of 
+herbicide application. 
+Use of STEEL" herbicide in accordance with label 
+directions is expected to result in normal growth of 
+rotational crops in most situations: however, various 
+environmental and agronomic factors make it 
+impossible to eliminate all risks associated with the 
+use of this product and, therefore, rotational crop 
+injury is always possible.
