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).

+desireable crop or ornamental plants which are senSitive to 2,4·0. 
+00 not permit spray mist containing it to drift onto them, since even 
+very small Quantities of spray, which may not be visible, can cause 
+severe tn)ury during both grOWing and dormant penods. Use coarse 
+sprays to minimize drift. With ground equipment, spray drift can be 
+lessened by keeping the spray boom as low as pOSSible. by apply. 
+.lng 20 gallons or more of 3t'lay per acre; by using no maIo than 20 
+pounds pressure with fla, fan or flooding flat fan nozzle tiPS; by 
+spraying when Wind velocity IS low; and by stopping all spraying 
+when wind exceed!> 6to 7 miles per hour, Do not apply With hollow 
+cone·type insectiCide or other nozzles that produce a fme dloplet 
+spray 
+With aircralt application, {',ilt can be lessened by applytng nolless
