Detailed Description

CRTP template base class for database backends.

Provides a template base class that eliminates duplicated lifecycle patterns across all database backend implementations. Uses CRTP (Curiously Recurring Template Pattern) for static polymorphism.

Issue #328: Create template base class for backend lifecycle

Design Goals:

• Eliminate ~150 lines of boilerplate per backend
• Centralize common lifecycle logic (constructor, destructor, create, type)
• Standardize initialization guard checks
• Allow backends to focus on database-specific implementation

Usage Pattern:

class postgresql_backend
    : public backend_base<postgresql_backend, database_types::postgres> {
public:
    static constexpr const char* backend_name() { return "postgresql_backend"; }
 
protected:
    friend class backend_base<postgresql_backend, database_types::postgres>;
    VoidResult do_initialize(const connection_config& config);
    VoidResult do_shutdown();
};
