Pull Request Overview
This pull request introduces a complete .NET 8.0 web API for task management, featuring a flexible architecture with multiple persistence options and a comprehensive scoring algorithm for task prioritization.
- Implements a full-stack task management system with both API endpoints and a web interface
- Provides two interchangeable storage implementations (in-memory and CSV-based) through dependency injection
- Includes a custom task scoring algorithm that considers priority, status, creation date, and other factors

The delete button has both btn-edit and btn-delete CSS classes applied. The btn-edit class should be removed as it's semantically incorrect for a delete action and may cause styling conflicts.

CSV parsing using Split(',') is vulnerable to breaking when task titles or descriptions contain commas. This will cause incorrect field parsing and potential data corruption. Consider using a proper CSV parser library or implementing proper CSV escaping/unescaping that handles quoted fields.

The CSV escaping is incomplete. This method only escapes quotes but doesn't wrap fields containing commas, quotes, or newlines in quotes. Fields containing commas will break the CSV parsing. A complete implementation should wrap such fields in quotes: \"field,with,commas\".

The GetTaskById method reads the entire CSV file for each lookup, which is inefficient for large datasets. Consider caching the task list in memory or implementing an index for better performance, especially since this method may be called frequently.

The magic number 10 for word length threshold should be extracted to a named constant to improve code readability and maintainability. Consider defining private const int LongWordThreshold = 10;.

This pull request introduces a new .NET 8.0 web API for managing tasks, with a flexible, testable architecture and CSV-based persistence. It includes a robust
TaskItemmodel with a custom scoring algorithm, two interchangeable task service implementations (CSV and in-memory), a full suite of xUnit tests, and an OpenAPI-enabled minimal API with endpoints for CRUD operations. The project is structured for maintainability and extensibility.
