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

 > Not a conflict. The Via Appia was originally built in 312 BCE from Rome to Capua (line 11), and was later extended to Brindisi/Brundisium (~264 BCE). Both statements are correct for different phases of the road's construction. Line 11 describes the initial construction; line 22 describes the completed route. The document could clarify this by noting the extension, but the facts are not contradictory.
