Add JSON/HTML content negotiation and clean up repository
Content Negotiation:
- New content_type.rs: Negotiate JSON vs HTML based on ?format=json
- JSON responses: Direct query results without template rendering
- HTML responses: Full Handlebars template rendering
- Example: /books?format=json returns JSON array
API Endpoints Now Support:
- /books?format=json - All books as JSON
- /book?id=1&format=json - Single book as JSON
- /search?q=Rust&format=json - Search results as JSON
- All existing HTML endpoints continue working
Cleanup:
- Removed old example configs (book_catalog, book_detail, book_named_params, howto)
- Removed old documentation (README_BOOK_CATALOG, README_PARAMETERS)
- Removed old template directories (people, books/all, etc.)
- Removed old template files (header.hbs, footer.hbs, etc.)
- Removed unused files (person.hbs, runit)
- Removed unused method: ParameterBinding::param_name()
Files Kept:
- conf/sqlite_serve.conf (unified production config)
- start.sh (unified start script)
- setup_book_catalog.sh (database setup)
- README.md (main documentation)
- ARCHITECTURE.md (architecture docs)
Build Status:
- 61 tests passing (+2 content type tests)
- 7 benign warnings (unused fields in generated types)
- Zero dead code
JSON verified working, all features functional.
