Add parameterized SQL queries with nginx variables
...
New Feature: sqlite_param Directive
- Allows passing nginx variables as SQL prepared statement parameters
- Supports query parameters ($arg_name), path captures ($1, $2), headers, etc.
- Safe SQL injection protection via rusqlite prepared statements
- Multiple parameters supported (bound in order to ? placeholders)
Implementation:
- New sqlite_param directive for adding query parameters
- Variable resolution using ngx_http_get_variable() FFI
- UTF-8 validation on all variable values
- Updated execute_query() to accept parameter array
- rusqlite::ToSql parameter binding
Examples:
- Book detail by ID: /book?id=1
- Genre filtering: /genre?genre=Programming
- Year range search: /years?min=2015&max=2024
New Files:
- conf/book_detail.conf: Parameter examples configuration
- server_root/book/detail.hbs: Book detail page template
- server_root/genre/genre.hbs: Genre filter page template
- start_book_detail.sh: Quick start script for params example
- README.md: Comprehensive project documentation
- README_PARAMETERS.md: Parameters feature documentation
Configuration:
- MainConfig now supports global_templates_dir
- ModuleConfig extended with query_params Vec
- Handler resolves variables at request time
- Template paths adjusted for exact location matches
All examples tested and working with both static and parameterized queries.

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
