Abimael MartellandClaude Fable 5 e1c160ddf2 review: retry only when invisible text was actually skipped; negative gate tests
- extract_page_text_items now reports skipped_invisible (4th return): the
  Tr-3 suppression sites set it, so the region extractor retries only when
  a recoverable layer exists. Blank pages and image-only scans without an
  OCR layer — the common scanned case — no longer pay a second
  content-stream parse.
- Negative tests: below-floor watermark layer and symbol-garbage layer are
  both rejected (region keeps only the raster placeholder). needs_ocr
  semantics for placeholder-only regions deliberately unchanged — that
  contract predates this PR and downstream pipelines handle it.
- Real scanned-book pages re-verified: recovery unchanged.
