tutorizeR 0.4.5

CRAN resubmission

Addressed CRAN resubmission feedback by adding DESCRIPTION references, removing \dontrun{} examples, requiring explicit output destinations for writing helpers, and moving example/vignette writes to tempdir().
Refreshed CRAN-facing source build exclusions so local Git metadata and old check/build artifacts are not included in source archives.

Finalized JOSE-oriented reviewer artifacts and metadata alignment.
Refreshed reproducibility and reviewer guidance docs.
Synchronized version fields for release publication.
Added JOSE preparation artifacts, educational use-case documentation, expanded vignettes, an example course module, publication-readiness tests, and pkgdown navigation for educational examples.
Recentered the review branch on JOSE software-submission requirements, clarified educational evidence boundaries, added CC-BY content licensing, and replaced internal smoke-test paths with installable example workflows.
Reworked the README as a package-facing overview and added pkgdown-oriented documentation articles for educational use cases and website maintenance.

Prepared final JOSS/CRAN-style release workflow:
- pinned package metadata version to 0.4.3;
- refreshed release checklist and finalization documentation;
- validated reproducible validation commands (R CMD build + R CMD check --as-cran --no-manual).
Documentation and review support:
- clarified JOSS reproducibility instructions in README;
- added “state of the art / alternatives” context and explicit limitations in manuscript.
Final release metadata:
- Description, CITATION.cff, and codemeta.json aligned with 0.4.3.

Added reusable local question-bank support (YAML/JSON):
- load_question_bank()
- validate_question_bank()
- MCQ reference chunks via {tutorizeR-mcq-ref}.
Added pedagogical linting:
- lint_source() with severity levels and rule codes (TRZ*).
- strict gate via lint_strict = TRUE in tutorize().
Added complete FR/EN i18n helper:
- tr() and dictionary files in inst/i18n/.
Extended conversion reports:
- richer tutorize_report fields (sections, chunks_total, mcq_explicit, mcq_from_bank, estimated_minutes, lint_summary).
- report export with write_tutorize_report() (JSON/YAML).
Added preview addin:
- launch_tutorizeR_preview_addin() with Source/Output/Diff/Lint/Logs tabs.
Added dissemination exports:
- export_lms_manifest() profiles: generic, canvas, moodle.
- export_tutorial_package() opt-in scaffold generation.
Added industrial hardening assets:
- regression fixtures + structural snapshot-style tests.
- stress batch test.
- CI coverage gate for core modules (parser/transform/validation/report) set to 80%.

Added canonical tutorize() API with conversion reports (tutorize_report).
Kept backward-compatible convert_to_tutorial() wrapper.
Added explicit validation helpers: validate_input() and validate_output().
Reworked conversion pipeline with structured parsing and deterministic label normalization.
Preserved narrative blocks and non-R fenced code blocks during conversion.
Added teacher tags: skip, exercise-only, solution-only, mcq, narrative-only, locked, and hints.
Added explicit MCQ block schema via fenced {tutorizeR-mcq} YAML blocks.
Improved convert_folder() with per-file error handling and summary reports.
Updated RStudio addins with option prompts.
Added CLI script at inst/scripts/tutorizeR-cli.R.
Added fixtures and extended test suite for Rmd/qmd core and edge scenarios.
Added vignettes, templates, audit/release docs, and release governance scaffolding.
