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).

+The amount in the table is based on gallons of finished spray per aore. 
+Different spray volumes will require appropriate changes in the amount of this 
+product added to one pint of fertilizer. Actd the required amount of this 
+product to one pint of fertilizer in a quart jar and shake to mix well. Let the 
+mixtl!re stand and examine it after 5 minutes and again after 30 minutes. The 
+product is incompatible if it balls up, forms flakes, sludges, gels, oily films, 
+layers, or other precipitates. If the precipitate can be suspended with / 
+agitation the oombination can be used if the equipment has vigorous agitation 
+throughout mixing and spraying operations. 
+In some cases, when incompatibility occurs, the addition of 1/4 teaspoon of a 
+oompatibility agent to the jar before adding this product ~ay solve the problem 
+(1/4 teaspoon is equal to 2 pints per 100 gallons of fertilizer). IF THIS DOES 
+1I0T WORK, DO NOT ATTEMPT THE ADDITION OF THIS PRODUCT TO THE FERTILIZER.

+and add to fertilizer with agitation 011. Tilen add balance of fertilizer and 
+apply immediately with agitation ON. DO Il0T leave spray mixture in tank 
+overnight.

+perennial or hard to kill weeds. To avoid injury, do not use with atrazine, 
+oil, or other adjuvants. --Preemergenoe: Appl!,' 1 1/3 - 2 213 pints pel' aore
