feat: 更新战斗系统模型结构和Redis消息处理

- 引入gredis依赖用于Redis消息处理
- 将战斗相关的枚举和结构体从info包迁移到model包
- 更新战斗结束原因、攻击值等类型的引用路径
- 添加新的zset工具包到工作区
- 修改Redis消息处理逻辑以正确解析gredis.Message类型
- 在战斗控制器中统一使用model包下的类型定义

+# ZSet
+This Go package provides an implementation of sorted set in redis.
+
+## Usage (go < 1.18)
+All you have to do is to implement a comparison `function Less(Item) bool` and a `function Key() string` for your Item which will be store in the zset, here are some examples.
+``` go
+package main
+
+import (
+	"fmt"
+
+	"github.com/liwnn/zset"
+)
+
+type User struct {
+	Name  string
+	Score int
+}
+
+func (u User) Key() string {
+	return u.Name
+}
+
+func (u User) Less(than zset.Item) bool {
+	if u.Score == than.(User).Score {
+		return u.Name < than.(User).Name
+	}
+	return u.Score < than.(User).Score
+}
+
+func main() {
+	zs := zset.New()
+
+	// Add
+	zs.Add("Hurst", User{Name: "Hurst", Score: 88})
+	zs.Add("Peek", User{Name: "Peek", Score: 100})
+	zs.Add("Beaty", User{Name: "Beaty", Score: 66})
+
+	// Rank
+	rank := zs.Rank("Hurst", true)
+	fmt.Printf("Hurst's rank is %v\n", rank) // expected 2
+
+	// Range
+	fmt.Println()
+	fmt.Println("Range[0,3]:")
+	zs.Range(0, 3, true, func(v zset.Item, rank int) bool {
+		fmt.Printf("%v's rank is %v\n", v.(User).Key(), rank)
+		return true
+	})
+
+	// Range with Iterator
+	fmt.Println()
+	fmt.Println("Range[0,3] with Iterator:")
+	for it := zs.RangeIterator(0, 3, true); it.Valid(); it.Next() {
+		fmt.Printf("Ite: %v's rank is %v\n", it.Item().(User).Key(), it.Rank())
+	}
+
+	// Range by score [88, 100]
+	fmt.Println()
+	fmt.Println("RangeByScore[88,100]:")
+	zs.RangeByScore(func(i zset.Item) bool {
+		return i.(User).Score >= 88
+	}, func(i zset.Item) bool {
+		return i.(User).Score <= 100
+	}, true, func(i zset.Item, rank int) bool {
+		fmt.Printf("%v's score[%v] rank is %v\n", i.(User).Key(), i.(User).Score, rank)
+		return true
+	})
+
+	// Remove
+	zs.Remove("Peek")
+
+	// Rank
+	fmt.Println()
+	fmt.Println("After remove Peek:")
+	rank = zs.Rank("Hurst", true)
+	fmt.Printf("Hurst's rank is %v\n", rank) // expected 1
+}
+```
+Output:
+```
+Hurst's rank is 2
+
+Range[0,3]:
+Peek's rank is 1
+Hurst's rank is 2
+Beaty's rank is 3
+
+Range[0,3] with Iterator:
+Ite: Peek's rank is 1
+Ite: Hurst's rank is 2
+Ite: Beaty's rank is 3
+
+RangeByScore[88,100]:
+Peek's score[100] rank is 1
+Hurst's score[88] rank is 2
+
+After remove Peek:
+Hurst's rank is 1
