Auto-commit: v2.7 Series Continuity & Book Number Awareness

- story/planner.py: enrich() and plan_structure() now extract series_metadata
  and inject a SERIES_CONTEXT block (Book X of Y in series Z, with position-aware
  guidance) into prompts when is_series is true.
- story/writer.py: write_chapter() builds and injects the same SERIES_CONTEXT
  into the chapter draft prompt; passes series_context to evaluate_chapter_quality().
- story/editor.py: evaluate_chapter_quality() accepts optional series_context
  parameter and injects it into METADATA so arc pacing is evaluated relative to
  the book's position in the series.
- ai_blueprint.md: Section 11 marked complete (v2.7), summary updated.
