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).

+SUPPLEMENTAL LABELING 
+AAtrex® Accu~Pak® Herbicide 
+EPA Reg. No. 100-756 
+This labeling must be in the possession of the actual product user at the time of 
+application. 
+Tile-Terraced Fields Containing Standpipes, 
+To ensure protection of surface water from runoff through standpipes and tile 
+outlets in terraced fields, any of the following options may be used: 
+1. Maintain a 66-foot setback around standpipes where this product may not be 
+applied, (this setback restriction applies to a standpipe when the connected 
+title outlet in a terraced field discharges within 66 feet of a point where field 
+surface water runoff enters a perennial or intermittent stream or river), or 
+2. Apply this product within the 66-foot setback, but immediately incorporate it 
+into the soil after application to a depth of 2-3 inches within area drained by 
+the tile inlet, or 
+3. Apply this product within the 66-foot setback if no-till combined with high crop 
+residue management practices are used in the area drained by the tile inlet. 
+High crop residue management means that little or no crop residue is 
+removed from the field during or after crop harvest.
