Fix BibleGateway scraping regex and add real-world test suite

- Fixed BibleScraper.scrapeChapter regex: changed from '-(\d+)$' to '\b(\d+)\b'
  The old regex only matched classes ending with dash-number, but BibleGateway
  uses class names like 'text-1' where the number is part of the class, not suffix
- Added tools/test_real_scrapers.py with persistent HTML caching
  Tests against cached targets until explicitly updated with --update-cache
  Tests all scrapers: BibleGateway, BibleHub interlinear, Wikisource Apocrypha
  Passes all 10 tests using cached data, ready for live testing

Fixes crash when reading OT books in Metanoia.

+Real-world Bible scraper test suite.

+Unlike unit tests with mocks, this actually hits the real scraping targets
+(BibleGateway, BibleHub, Wikisource) and caches results. This allows:
+1. Detection of real scraping failures (markup changes, rate limits, etc.)
+2. Iterative debugging with cached results
+3. Backoff and retry testing
+4. Performance monitoring
