Function emit_declarations_from 

pub fn emit_declarations_from<T: DeclLike>(
    store: &mut FactStore,
    prov: &FactProvenance,
    source: &T,
) -> usize

Convenience: emit a declaration fact for every entry a DeclLike source yields. The trait keeps this module free of a hard plsql-symbols dependency (which would invert the layer order — symbols depends on ir, not the reverse).
