GET /tasks/upcoming

Expose an endpoint that returns tasks scheduled to run soon, based on a future time window.

What to implement:

New route: GET /tasks/upcoming

Query params:

window (minutes, default 60)

limit, offset (optional)

Return tasks where:

status = 'pending' & run_at is between NOW() and NOW() + interval 'window minutes'

Order results by run_at ascending.

About the window parameter
window defines how far into the future to look.
Example:
GET /tasks/upcoming?window=30 , This returns pending tasks scheduled in the next 30 minutes.

DB logic:

Select tasks where:

status = 'pending'

run_at is between NOW() and NOW() + interval 'window minutes'

Order by run_at ascending

Expected result

A filtered, chronological array of upcoming tasks.

Empty array if nothing is scheduled in the window.

在代码库中查找现有的任务路由，可能在 routes/ 或 controllers/ 目录中。需要在那里添加新的 GET /tasks/upcoming 端点，使用描述的过滤器（status='pending'，run_at 在窗口内）查询 tasks 表。检查其他端点如何处理查询参数和数据库查询，以遵循项目的模式。通过运行服务器并使用不同的 window 值调用端点进行测试。
