Build term-info References from the full has_reference set (deduped, full URLs)

[Robbie1977]

What

Build the term-info References list from the complete has_reference set rather than only pubs.

has_reference edges are partitioned by typ into pubs / def_pubs / pub_syn; their union is the term's full reference list. For anatomy classes pubs is empty, so References were previously reconstructed downstream from synonym/definition markdown — losing the structured DOI/PMID/FlyBase links.

This adds a consolidation step in the term-info serialiser that:

• unions pubs ∪ def_pubs ∪ pub_syn[].pub (+ pub_syn[].pubs);
• de-duplicates by short_form (drops duplicate edges and the Unattributed placeholder);
• emits full external URLs built from the pub-node fields — flybase.org/reports/<FBrf>, …/pubmed/?term=<PMID>, https://doi.org/<DOI>.

Inline definition microrefs and the synonym publication strings are unchanged — only the References row draws from this list.

Verified

Run against the live SOLR blob:

• medulla FBbt_00003748 → 9 distinct references, full URLs, no Unattributed, no dupes.
• PPL101 FBbt_00100243 → 10 distinct, now including the def-only Truman/Otto/Sayin pubs that previously could not be linked.
• pub term FBrf0224194 → unchanged (single pub via existing path).

Follow-up

• VFBquery point release + term-info cache refresh.
• Java VFBProcessTermInfoVFBqueryJson can then render icons straight from Publications (reverts the icon-removal in uk.ac.vfb.geppetto 9f102da).
