Build Task Filtering System

**Title:** Implement Multi-Criteria Task Filtering with URL State

## Problem Statement

Users cannot filter tasks by status, priority, category, or due date, making it difficult to focus on specific subsets of tasks. A comprehensive filtering system is essential for task management productivity.

## Proposed Solution

Create a flexible filtering system featuring:

* Filter by status (All, Active, Completed)
* Filter by priority (Low, Medium, High)
* Filter by category/tags
* Filter by due date range
* Combine multiple filters
* URL parameter state for shareable filters
* Clear all filters button
