refactor: rename 'recit' to 'narrative' for English code naming

- Rename store: recit.js → narrative.js (useRecitStore → useNarrativeStore)
- Rename templates: recit.php/json.php → narrative.php/json.php
- Rename blueprint: recit.yml → narrative.yml
- Update all imports and references in Vue/JS files
- Update PHP template references and data attributes
- Update CLAUDE.md documentation
- Create comprehensive README.md with English-French dictionary

The dictionary section maps English code terms to French content terms
for easier navigation between codebase and CMS content.
