Add GLBRC UFMP fermentation community (closes #17)

[cmungall]

Summary

• Adds new community YAML for the GLBRC ultra-filtered milk permeate (UFMP) fermentation bioreactor community (PMID:37324413, doi:10.3389/fbioe.2023.1173656)
• 282-day continuous anaerobic bioreactor converting dairy coproducts into renewable chemicals via carboxylate platform fermentation
• 10 MAG-resolved taxa spanning Actinobacteriota (Olsenella, Bifidobacterium, Pauljensenia), Firmicutes (Clostridium, Agathobacter, Acidaminococcus), and Spirochaetota
• 3 ecological interactions modeling the Actinobacteriota-Firmicutes cross-feeding network: lactose degradation -> organic acid production -> chain elongation to medium-chain fatty acids (butyrate, hexanoate, octanoate)
• 8 metabolites with CHEBI terms, environmental factors (35C, pH 5.5, anaerobic, 6-day HRT), and metagenome dataset (PRJNA768492)

Test plan

• just validate kb/communities/GLBRC_UFMP_Fermentation_Community.yaml passes with no issues

Closes #17

Pull request overview

This PR adds a new community YAML entry for the GLBRC ultra-filtered milk permeate (UFMP) fermentation bioreactor community, as requested in issue #17. The community models a 282-day continuous anaerobic bioreactor converting dairy coproducts into renewable chemicals via carboxylate platform fermentation, based on PMID:37324413.

Changes:

• Adds a new community YAML file with 10 MAG-resolved taxa, 3 ecological interactions modeling the Actinobacteriota-Firmicutes cross-feeding network, 8 metabolites with CHEBI terms, environmental factors, and a metagenome dataset reference.
• All schema enums are valid and the file structure matches the LinkML schema definition.

The CHEBI ID for lactate is inconsistent with the rest of the codebase. CHEBI:422 is specifically "(S)-lactate", whereas every other community file in the repository (DVM_Triculture.yaml, Desulfovibrio_Methanococcus_Syntrophy.yaml, Trichoderma_Lactate_Platform.yaml, Phormidium_Alkaline_Consortium.yaml, Polaromonas_Vanadium_Reduction_Community.yaml, Panzhihua_Vanadium_Titanium_Tailings.yaml) consistently uses CHEBI:24996 for the general "lactate" term. This should be changed to CHEBI:24996 in all three occurrences (lines 308, 336, 390) for consistency.

Same CHEBI ID inconsistency as noted at line 308. CHEBI:422 ("(S)-lactate") should be CHEBI:24996 ("lactate") to match the established codebase convention (see e.g. DVM_Triculture.yaml:115, Trichoderma_Lactate_Platform.yaml:140).

The CHEBI ID for acetate is inconsistent with the rest of the codebase. CHEBI:15366 is "acetic acid" (the protonated form), while every other community file in the repository consistently uses CHEBI:30089 for "acetate" (the conjugate base). See e.g. DVM_Triculture.yaml:120, Desulfovibrio_Methanococcus_Syntrophy.yaml:90, Trichoderma_Lactate_Platform.yaml:144, and many others. This should be changed to CHEBI:30089 with label acetate.

The NCBITaxon ID and label are at the phylum level (NCBITaxon:203691 = Spirochaetota), but the preferred_term identifies this organism as "RUG023 sp." which is a genus-level designation (a GTDB-defined genus within Spirochaetota). Every other taxonomy entry in this file and across the codebase uses genus-level or species-level IDs (e.g., NCBITaxon:133926 for Olsenella, NCBITaxon:1485 for Clostridium). If a genus-level NCBI Taxonomy ID is not available for RUG023, the label should at minimum be updated to clarify this mismatch, or the notes should explain that RUG023 is a GTDB genus without an NCBI Taxonomy entry and that the phylum is used as a placeholder.

	as substrate for chain elongation by Firmicutes. RUG023 is a GTDB-defined genus within
	Spirochaetota that currently lacks a genus-level NCBI Taxonomy identifier; the

The evidence snippet for this Spirochaetota/RUG023 taxon discusses Firmicutes chain elongation, not the claimed ethanol production by RUG023 sp. SPH2. The snippet says "members of the Firmicutes phylum contribute to the chain-elongation-mediated production of butyric, hexanoic, and octanoic acids" — this does not support the explanation that "RUG023 sp. SPH2 produces ethanol used as chain elongation substrate." A more relevant snippet specifically about ethanol production by Spirochaetota members should be used, or the supports value should be changed to PARTIAL with an explanation noting the indirect relationship.
