v1.1.0 — arXiv verification and Codex plugin packaging

Highlights

• Adds deterministic arXiv ID verification alongside DOI, PMID, NCT, ISBN, and title-only citation handling.
• Adds machine-readable lookup traces via lookupVerified and resolverOutcomes so agents can explain citation verdicts without guessing.
• Adds --cache for stable, faster repeated registry checks.
• Adds Codex Desktop plugin metadata and updates Claude/Codex medical fact-check skill guidance to prefer the local evidentia binary.
• Expands regression coverage and benchmark cases for preprints, fabricated identifiers, and manual-review sources.

Verification

• npm test
• npm run build
• live sample: arXiv:1706.03762 verifies as Tier 1 and a fabricated DOI is flagged as Tier 4.

Note: npm registry publication is still pending npm authentication; the attached tarball is the packed evidentia@1.1.0 artifact.
