Separate pepper SynCom preparation from measured ecology and inferred mediation #1687

CommunityMech:000104, PMID39858916. Remove inoculum-preparation node and workflow arrow. Preserve three biological endpoints and author-proposed diversity-to-enrichment-to-growth model as HYPOTHESIZED: relative OTUs and random-forest/correlation associations are not causal mediation. Avoid reciprocal-fitness and colonization typings. Preserve four canonical taxa and #1216/#1217 fixes. Keep Scedosporium genus decrease distinct from OTU451 increase. Close only after protected-main merge.
