pdf2wiki 0.2.3 — QA flags report + batch error_class rollup

QA + diagnostics from an external review of the repo. No breaking changes — every existing command
and flag behaves the same. Test suite 103 → 107 passing.

pip install --upgrade pdf2wiki    # 0.2.3

Added

• pdf2wiki qa flags PATHS... — a per-book report of the code blocks where the VLM diverged from the
  byte-clean text layer (_code_flag), or where hybrid indentation failed a Python ast check
  (_indent_flag), read straight from blocks.json. Pass several books' blocks.json and it ranks them
  by flagged count (which books to trust least); pass one and it lists each flagged block (page /
  language / snippet). These are the highest-signal spots to spot-check a conversion.

Changed

• Batch summary rolls up error_class — a partial batch now prints, e.g.
  5 book(s) not done — by class: permanent×3, timeout×1, fetch×1 (plus the slug list), so a cluster of
  same-kind failures reads as one diagnosis instead of N separate slugs. Exit code unchanged.
