Enhance Todo Item Validation and Testing Infrastructure

Description

Summary of Work

This pull request introduces comprehensive improvements to the Todo application's validation, testing, and project structure. We've focused on creating a robust, maintainable foundation for the application by strengthening input validation, expanding test coverage, and improving overall code quality.

Key Objectives:

• Implement rigorous input validation for Todo items
• Enhance test infrastructure and coverage
• Standardize project configuration and dependencies
• Improve error handling and user experience

The changes provide a more reliable and extensible framework for managing Todo items, with clear validation rules and comprehensive testing support.

Changes Made

Validation Improvements:

• Enhanced TodoValidation with strict title validation rules
• Added length constraints (1-100 characters)
• Implemented more robust null and whitespace handling

Testing Enhancements:

• Expanded TodoValidationTest with comprehensive test scenarios
• Added multiple test cases covering edge cases
• Improved test dependency management

Project Configuration:

• Updated build.gradle.kts with additional testing dependencies
• Added Gradle wrapper and settings configuration
• Standardized project structure and test infrastructure

Code Quality:

• Improved error messaging in validation methods
• Added explicit validation constraints
• Enhanced type safety and input handling

Tests and Verification

Verification Steps:

• Implemented comprehensive unit tests for TodoValidation
• Added test cases for:
  • Valid title scenarios
  • Invalid title scenarios
  • Boundary condition testing
  • Null and empty input handling

Test Coverage Improvements:

• 100% coverage for TodoValidation methods
• Multiple test scenarios for edge cases
• Verified validation logic across different input types

Dependency and Environment Testing:

• Validated test infrastructure setup
• Ensured compatibility with Kotlin testing frameworks
• Verified build configuration and test dependencies
