## ⚠️ Breaking Changes

### `ExecWithSubagent` signature changed

The function now accepts an explicit reasoning argument between `model` and `systemPrompt`.

**Before:**
```go
func ExecWithSubagent(ctx context.Context, task, sessionIDInput, model, systemPrompt string, excludedTools []string, parentSessionID string) (string, error)
```

**After:**
```go
func ExecWithSubagent(ctx context.Context, task, sessionIDInput, model, reasoning, systemPrompt string, excludedTools []string, parentSessionID string) (string, error)
```

**Migration:**
```go
// Old
exec.ExecWithSubagent(ctx, task, sessionID, model, systemPrompt, excludedTools, parentSessionID)

// New: preserve the previous model-selected reasoning behavior
exec.ExecWithSubagent(ctx, task, sessionID, model, "", systemPrompt, excludedTools, parentSessionID)

// New: explicitly select a reasoning level
exec.ExecWithSubagent(ctx, task, sessionID, model, "low", systemPrompt, excludedTools, parentSessionID)
```

<details>
<summary>翻譯</summary>

`ExecWithSubagent` 在 `model` 與 `systemPrompt` 之間新增 `reasoning` 參數。既有呼叫端可傳入空字串以保留原本由模型設定決定 reasoning 的行為，或改為明確指定 reasoning level。
