- Create pagination package with Params and Response structs - Add FindActiveByUserIDWithPagination and CountActiveByUserID methods to HabitRepository interface - Implement pagination in SQLite repository using LIMIT and OFFSET - Update GetUserHabitsHandler to support optional pagination parameters - Modify HTTP endpoint to parse 'page' and 'page_size' query params (default: page=1, page_size=50, max=100) - Add GetUserHabitsResponse DTO with pagination metadata - Maintain backward compatibility - endpoint works with and without pagination params - Add comprehensive tests for pagination logic in repository, handler, and pagination package - Update all mock repositories to implement new pagination methods
