Blueprint v1.5.0: AI Context Optimization — Dynamic Characters & Scene State

- writer.py: Dynamic character injection — only POV + beat-named characters
  are sent to the writer prompt, eliminating token waste and hallucinations
  from characters unrelated to the current scene.
- writer.py: Smart tail truncation — prev_content trimmed to last 1,000 tokens
  (the actual chapter ending) instead of a blind 2,000-token head slice,
  preserving the exact hand-off point for continuity.
- writer.py: Scene state injected into char_visuals — current_location,
  time_of_day, and held_items now surfaced per relevant character in prompt.
- bible_tracker.py: update_tracking expanded to record current_location,
  time_of_day, and held_items per character after each chapter.
- core/config.py: VERSION bumped 1.4.0 → 1.5.0.
- README.md: Story Generation section and tracking_characters.json schema
  updated to document new context optimization features.
