Add comprehensive project timeline and task documentation encompassing entire development process

[Copilot]

This PR addresses the need for current, logical, and comprehensive project timeline and task documentation that encompasses the entire process of building the StudyPlanner application.

Problem

The repository lacked proper project management documentation, making it difficult for contributors and stakeholders to understand:

• Current development status and completed work
• Logical progression of development phases
• Specific actionable tasks with priorities
• Overall roadmap from inception to deployment

Solution

Created three comprehensive documentation files that provide a complete view of the project lifecycle:

📋 PROJECT_TIMELINE.md

A detailed 18-week development roadmap organized into 7 logical phases:

• Phase 1-2: Project Foundation & Backend (Weeks 1-6) ✅ Complete
• Phase 3: Frontend Development (Weeks 7-10) 🔄 In Progress
• Phase 4: AI Integration & Advanced Features (Weeks 11-14) 📋 Planned
• Phase 5-6: Integration, Testing & Deployment (Weeks 15-18) 📋 Planned
• Phase 7: Maintenance & Enhancement 📋 Ongoing

Includes milestone tracking, risk assessment, success metrics, and resource requirements.

🛠️ DEVELOPMENT_TASKS.md

Detailed task breakdown with specific actionable items:

• Immediate priority tasks (ESLint fixes, HTML cleanup, database connection)
• Current sprint tasks (responsive design, UI enhancement)
• Future development tasks (AI integration, analytics dashboard)
• Task prioritization matrix with time estimates
• Sprint planning guidelines and Definition of Done

📖 Updated README.md

Completely restructured with:

• Current vs planned features with status indicators
• Modern installation and setup guide
• Technology stack breakdown and project structure
• API documentation and development workflow
• Contributing guidelines and support information

Key Features

• Current & Accurate: Reflects actual project state (backend complete, frontend in progress)
• Logical Progression: Well-structured phases following software development best practices
• Comprehensive: Covers entire development lifecycle from setup to maintenance
• Actionable: Specific tasks with clear priorities and acceptance criteria
• Maintainable: Weekly review schedule and update framework

Additional Improvements

• Removed node_modules from git tracking for cleaner repository
• Maintained all existing functionality (tests still passing)
• Added professional project management structure for open source contributions

The documentation now provides stakeholders and contributors with a clear understanding of where the project stands, what work remains, and how to contribute effectively to the StudyPlanner application development.
