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

+) 
+PROPANIL eOEDf acts only on grasses and weeds which have already germinated. (Maximum activity u!.uaUy is not apparent until 
+5 to 7 days af.er application.) To prevent more weeds from germinating after treatment, fields should be ftooded within 24 hours after 
+spraying, or as soon as possible al'ter 24 hQurs. Flooding after spraying win improve the grass control after PROPANIL SOEDF 
+treatment. In eases where nooding of the field would not be complete wrthin seven days or tess after application of PROPANIL SOEDF, 
+it is best to treat a. portion of the field, floed that treated portion, and thon treat the remaind~r. This wilf heIRPJ~v~=!t~!!,~statJon of 
+weeds and grasses. Hloher rates 5 - 7.5 Ibs. may be necessary on the remaInder since the grass wilt be more mature. 
+If the rice is too small to maintain a neod on the fleW, treatment should 00 delayed unbl rice Is large enough. The grass may then 
+be farge enough to require 5 - 7.5 Ib$. of PROPANll80EDF. Avoid treatment if rain threatens within 8 houR or If high winds may 
+cause uneven application c)r drift. 
+In case of unseasonably coofweather, higher rates (5 - 7.5IbaJacre) of PROPANIL 8O€DF may be necessary. The number of leaves 
+of barnyard or watergrass determine the til'llt' and amount of PROPANfL 80EDF to spray, regardless of the size of the rice. 
+The temperature a few days before and after applying PROPANll 80EDF herbicide has an important bearing on the weed kimng 
+activity. The actiVity increase .. 3S dally maximum temperature'S increase above 75°F and decreases as the daily maximum 
+temperatures decline below 7SoF. 00 not apply PROPANIL 8OEOF herbicide when ma)('nnum temperatures have been or are 
+expee1:ed to stay below 6S
+G
+F or to go -above 100~. low temperaruce at Ume of application is not 90 important as long aa it warms 
+up later during the day. 
+The grower should inspect fields frequently to determine p.roper time of application. The ideal application time is when most 
+bamyardgras8 has one to three leaves, with only an occasional plant having four leaves. During drought conditions grasses may reach 
+the three leaf stage while still quite short or stunted, so special attention to stage of growth is necessary In those situations to avoid 
+grasses becoming foo mature for be$t resWts. 
+Apply 3.75 ~ 5.0 Ibs. of PROPANll 80EDF per acre when most grass has reached the one to three feaf stage, Use 5.0 - 7.5Ibs. of 
+PROPANIL 80EDF per acre ifgrasscs are targer, with most in the four to six leaf stage. Mix PROPANll80EDFthoroughly with water 
+for spraying, w:.ing vigorous. mechanical agitation. For AERIAL APPLICATION dilute the proper amount of PROPANIL SOEDF with 
+10 to 12 gallons of water per acre If humidities are low, incre~se to 12 to 15 gallons of water per acre. For GROUND EQUIPMENT 
+dilute the prl)per afnollnt of ?ROPM~IL 80EOF with 15 to 25 gallons of water per acre. Lesser amounts of water onli3n give inadeqtlate 
+coverage and may cause poor resutts. 
+If fields eannot be completely drained $0 that all of the grass is exposed, a higher dosage of PROPANIL 80EDF (5 ~ 7.5IbsJacre) 
+must be used, 
+NOTE: VVhcn PROPANfL 80EDF is. applied, especially after the fourth Icarstage of growth aftho rice, under some conditions, visible 
+leaf injury on rice may result However, the rice pl-dnts quick~:I outgrow such injur/ when caused by the later applications. 
+USE IN CALIFORNIA ONLY _1fJhere rice fields are not completely drained. 
+To control watcrgrass, app~y PROPANll 80EDF 30 to 45 days after planting, before rice is ful~J tiller-cd, ..... 'hen watergrass extends 6 
+to a inches above water surface. If rice has a deep ncod, water leve! may be lowered to 3-4 inches over highest part of field to expose 
+6-8 inches of water grass. ('M"1en lowering water level, do so slowly to avoid pulling down rice plants.) Use 5 Ibs. pe( acre .f mostgrnss
