Separate pleuromutilin parent enrichment and assembly workflow from five-strain graph #1711

CommunityMech:000300; PMID:42133144. Remove three experimental assembly/isolation workflow nodes and the natural-En4-only core-specialization node from this artificial-five-strain graph, preserving natural positives as discussion context. Retain 91.97% degradation and qualified proposed metabolic products/pathways. Remove two workflow/out-of-scope arrows and unsupported SYNTROPHY/NICHE_PARTITIONING classifications. Public supplement Table S2 shows no inhibition zones, not metabolic exchange. No new topology in this repair. Close only after protected-main merge.
