Build a Task Tracker API with Spring Boot

Problem/Feature Description

A development team needs a REST API for their task tracking tool. The API is built with Spring Boot and Java. A React frontend on a separate domain will consume it.

The API needs the following endpoints:

• GET /api/tasks -- list all tasks (supports ?status=open&assignee=john query filters)
• GET /api/tasks/{id} -- get a single task
• POST /api/tasks -- create a new task (accepts title, description, priority HIGH/MEDIUM/LOW, assignee)
• PATCH /api/tasks/{id} -- update a task (change status, reassign, edit details)
• DELETE /api/tasks/{id} -- delete a task
• POST /api/tasks/{id}/comments -- add a comment to a task (accepts author, text)

Use an in-memory data store. Tasks should have id, title, description, status (OPEN, IN_PROGRESS, DONE), priority, assignee, comments, and createdAt fields.

Output Specification

Produce:

• TaskController.java -- REST controller with all endpoints
• Task.java -- Task model
• CreateTaskRequest.java -- Request DTO for task creation
• SecurityConfig.java -- Security configuration
• pom.xml -- With all required dependencies
