Changes in version 0.0.1.4                       

  - Added shared multi-model support across the simulation pipeline so
    simulate_treatment(), run_ai_on_chapters(),
    run_ai_on_chapters_one_turn(), and run_ai_cumulative_chapters() can
    accept length(model) >= 1.
  - Added a model column to raw simulation outputs and updated
    downstream summaries to preserve model-specific results instead of
    collapsing across models.
  - Added summarize_identity_adherence() and
    summarize_identity_match_rates() to tally whether models adopt the
    requested identity and to summarize per-model adoption rates.

                       Changes in version 0.0.1.3                       

  - Renamed simulate_treatment() output columns to use treatment
    terminology instead of chapter.
  - Simplified summarize_treatment_results() to summarize
    treatment-level outputs only.
  - Updated README and treatment documentation/examples to match the
    revised treatment workflow API.

                        Changes in version 0.0.1                        

  - Added BugReports field in DESCRIPTION pointing to the GitHub issue
    tracker.
  - Fixed README title grammar: "Do books really change lives?".
  - Replaced placeholder tests with basic offline tests for prompt
    builders and chapter summary helpers.
  - Updated summarize_chapter_scores documentation to match current
    delta/gap output columns.
