Correct Rifle uranium graph source scope and late-phase outcome #1766

Rifle_Uranium_Reducing_Community.yaml (CommunityMech:000060): PMID14532040 reports increased aqueous uranium during the later sulfate-reducing phase, not continued sulfide-mediated immobilization. PMID18843300 is a Geobacter uraniireducens transcriptome, not Anaeromyxobacter hydrogen metabolism. PMID19346346 and PMID18456853 are Oak Ridge, not Rifle; PMID12788780 is a high-salinity system and PMID36889400 is an isolate assay. Remove the unsupported Anaeromyxobacter and complementary Desulfosporosinus transfer nodes and the sulfate-to-immobilization arrow. Retain early enrichment/removal and later succession/sulfate observations, with proposed mediation explicitly PARTIAL and no nanoparticle size, species-resolved rate, reciprocal fitness or demonstrated competitive exclusion. Preserve canonical taxonomy outside the graph pending the separate non-graph finding. Fresh primary abstract and cached primary full text agree on the later adverse outcome. No new topology.

Dedup: fresh all-state issue titles/bodies and ignored/hidden-inclusive local search with .git/docs/site/references_cache excluded; relevant caches separately inspected. Matching issues read, not duplicates of these findings. Comments/PRs not exhaustive. Source-based self-adversarial review, not independent approval. Graph-repair issues close only after protected-main merge.
