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).

+Dear Niamh McMahon, 
+The a
+mended label referred to above, submitted in connection with registration under the Federal 
+Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended, is acceptable. This approval 
+does not affect any conditions that were previously imposed on this registration. You continue to 
+be subject to existing conditions on your registration and any deadlines connected with them. 
+A st
+amped copy of your labeling is enclosed for your records. This labeling supersedes all 
+previously accepted labeling. You must submit one copy of the final printed labeling before you 
+release the product for shipment with the new labeling. In accordance with 40 CFR 152.130(c), 
+you may distribute or sell this product under the previously approved labeling for 18 months 
+from the date of this letter. After 18 months, you may only distribute or sell this product if it 
+bears this new revised labeling or subsequently approved labeling. “To distribute or sell” is 
+defined under FIFRA section 2(gg) and its implementing regulation at 40 CFR 152.3. 
+Should you w
+ish to add/retain a reference to the company’s website on your label, then please be 
+aware that the website becomes labeling under FIFRA and is subject to review by the Agency. If 
+the website is false or misleading, the product would be misbranded and unlawful to sell or 
+distribute under FIFRA section 12(a)(1)(E). 40 CFR 156.10(a)(5) lists examples of statements 
+EPA may consider false or misleading. In addition, regardless of whether a website is referenced 
+on your product’s label, claims made on the website may not substantially differ from those 
+claims approved through the registration process. Therefore, should the Agency find or if it is 
+brought to our attention that a website contains false or misleading statements or claims 
+substantially differing from the EPA approved registration, the website will be referred to the 
+EPA’s Office of Enforcement and Compliance.

+with FIFRA section 6.
