feat: Phase 1 基盤設定完了 - Flask ポモドーロタイマー

[naokikurihara-0518]

This pull request introduces the initial foundation for a Pomodoro timer web application using Flask, HTML/CSS/JavaScript, and a layered architecture. It includes comprehensive setup for configuration management, application factory, project structure, documentation, and quality assurance through testing. The changes establish the groundwork for future feature development and ensure high maintainability and test coverage from the start.

Project Structure & Architecture:

• Established a layered project structure with clear separation of concerns (presentation, application, domain, infrastructure) and added descriptive __init__.py files for each layer. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]

Configuration & Application Factory:

• Implemented robust environment-based configuration management in app/config/settings.py for development, production, and testing, including database URIs, timer settings, and logging.
• Developed an application factory (app/factories/app_factory.py) to create and configure the Flask app, initialize extensions (SQLAlchemy, SocketIO, CORS), register routes, and error handlers.

Documentation & Planning:

• Added a detailed Japanese README.md outlining project overview, architecture, features, quickstart, environment variables, contribution guidelines, and quality goals.
• Created features.md listing all planned features, technical requirements, and development phases for the Pomodoro timer app.

Testing & Quality Assurance:

• Included a comprehensive TEST_REPORT.md summarizing test coverage (98%), test types (unit, integration), and quality metrics, demonstrating a strong commitment to reliability and maintainability.

Entrypoint & Metadata:

• Added main.py as the application entrypoint, handling environment selection, app creation, debug output, and server startup via SocketIO.
• Introduced basic package metadata in app/__init__.py.

These changes provide a solid, well-documented, and testable foundation for further development of the Pomodoro timer web application.✨ 新機能:
