Blueprint v2.4-2.6: Style Rules UI, Lore RAG, Thread Tracking, Redo Book

v2.4 — Item 7: Refresh Style Guidelines
- web/routes/admin.py: Added /admin/refresh-style-guidelines route (AJAX-aware)
- templates/system_status.html: Added 'Refresh Style Rules' button with spinner

v2.5 — Item 8: Lore & Location RAG-Lite
- story/bible_tracker.py: Added update_lore_index() — extracts location/item
  descriptions from chapters into tracking_lore.json
- story/writer.py: Reads chapter locations/key_items, builds LORE_CONTEXT block
  injected into the prompt (graceful degradation if no tags)
- cli/engine.py: Loads tracking_lore.json on resume, calls update_lore_index
  after each chapter, saves tracking_lore.json

v2.5 — Item 9: Structured Story State (Thread Tracking)
- story/state.py (new): load_story_state, update_story_state (extracts
  active_threads, immediate_handoff, resolved_threads via model_logic),
  format_for_prompt (structured context replacing the prev_sum blob)
- cli/engine.py: Loads story_state.json on resume, uses format_for_prompt as
  summary_ctx for write_chapter, updates state after each chapter accepted

v2.6 — Item 10: Redo Book
- templates/consistency_report.html: Added 'Redo Book' form with instruction
  input and confirmation dialog
- web/routes/run.py: Added revise_book route — creates new Run, queues
  generate_book_task with user instruction as feedback
