[LifeSci Skill] Make Entrez PubMed citations clickable

[phorward-deployed]

Summary

Make PMIDs and DOIs clickable in user-facing Entrez results. The change applies to tables, bullets, parentheticals, and source lists; raw JSON/XML stays unchanged.

Also bumps life-science-research from 1.0.2 to 1.0.3 so downstream installs pick up the new guidance.

Validation

• installed the branch plugin locally and compared it with the curated version
• verified tables, bullets, prose, source lists, and raw JSON output
• quick_validate.py
• git diff --check origin/main...HEAD

Before/after screenshots

Before

PubMed identifiers and DOIs were rendered as plain text.

After

The same prompt renders every PMID and DOI as a clickable hyperlink.
