Replace the local src/source PDF slice with the standalone
@citation-evidence/evidence-source package (link:../evidence-source).
- src/source/index.ts is now a thin façade re-exporting the ingest core
and browser upload helpers from the package
- viewer-url stays local (viewer concern) but takes PdfByteStore from
the package
- extracted ingest/extract/fingerprint/byte-store/upload files removed
- anchor-source round-trip integration test now exercises the package
across the repo boundary
Full suite (125 tests), typecheck, and lint all green.
