/**
 * @fileoverview Ontology-backed semantic concept identifiers attached to each
 * tool's `_meta['io.mcpmed/concepts']` field. Each constant is a stable URI
 * from an established vocabulary (Schema.org or EDAM) paired with a human
 * label — no free-text placeholders.
 *
 * This implements the semantic concept mapping proposed in MCPmed
 * (Flotho et al., Briefings in Bioinformatics, 2026; doi:10.1093/bib/bbag076)
 * with resolvable URIs rather than the placeholder strings used in that paper's
 * reference implementations.
 *
 * Namespacing: the `io.mcpmed/concepts` key is a proposal for MCPmed-aligned
 * servers. If MCPmed standardizes a different key, this is a single rename.
