## Features

### Custom Dependency Timeout - Specify timeout via `Wait{ID: taskID, Delay: duration}` - Default timeout is 1 minute when not configured

### Dependency Failure Handling Strategy - Added `Stop` and `Skip` handling modes - `Stop`: Halt entire dependency chain on failure (default) - `Skip`: Skip failed dependency and continue executing current task - Configure failure behavior via `Wait{ID: taskID, State: Skip}`

### Examples ```go // Failure handling strategy taskID, _ := scheduler.Add("@daily", func() error { return processData() }, "Data processing", []Wait{ {ID: taskA, State: Skip}, // Skip if taskA fails, continue execution {ID: taskB, State: Stop}, // Stop if taskB fails (default) })

// Custom timeout + failure strategy combination taskID, _ := scheduler.Add("@daily", func() error { return processData() }, "Data processing", []Wait{ {ID: taskA, Delay: 30 * time.Second, State: Skip}, // Wait 30s, skip on failure {ID: taskB, Delay: 10 * time.Second, State: Stop}, // Wait 10s, stop on failure })

// Legacy version (deprecated in v2..) taskID, _ := scheduler.Add("@daily", func() error { return processData() }, "Data processing", []int64{taskA, taskB}) ```

## Refactor

### Compatibility Guarantee - Legacy code runs without modification - Maintains `[]int64` dependency support (deprecated in `v2..`) - `WaitState` zero value is `Stop`, ensuring default behavior unchanged

## Deprecation Notice

### Features Removed in `v2..` - `[]int64` format: Migrate to `[]Wait` format for full feature support ```go // Old format []int64{taskA, taskB}

  // New format
  []Wait{{ID: taskA}, {ID: taskB}}
  ```
