Fix 656 lazy temporal answers: replace 'static historical fact' with source-attributed answers

- Updated perspective.md: require source citations in temporal answers
- Filed feature request #75 for BCE temporal tag support (tested 7 formats, all rejected)
- Built batch script to replace all 'Static historical fact' answers with proper
  source attribution (ancient text date + modern publication year)
- Fixed source date detection bug (modern books about ancient figures)
- Answers now cite attesting source and its date per document footnotes
