Add book catalog example with global/local template system
Features:
- Global template configuration (sqlite_global_templates directive)
- Template path resolution relative to location
- Automatic template loading from directories
- Local templates override global templates
- Content handler installation via directive setter
Book Catalog Example:
- Complete working example with 10 technical books
- SQLite database with setup script
- 4 browseable pages (all, programming, databases, computer-science)
- Shared global templates (header, footer, book_card partial)
- Category-specific local templates with unique theming
- Responsive gradient UI design
- Working navigation and filtering
Configuration:
- sqlite_global_templates: HTTP main-level directive for shared templates
- sqlite_template: Location-level directive (sets content handler)
- Template resolution: {doc_root}{uri}/{template_name}
- All .hbs files in directories auto-loaded as partials
Technical improvements:
- Fixed content handler setup (not phase handler)
- Proper HttpModuleMainConf and HttpModuleLocationConf traits
- Template directory scanning and registration
- Error handling with debug logging
