fix: disable gesture module on Treeland

[yixinshark]

Add gesture to the Treeland module denylist so dde-session-daemon does not load the legacy gesture module under Treeland.

将 gesture 加入 Treeland 模块禁用列表,避免 dde-session-daemon 在 Treeland 环境加载旧的 gesture 模块。

你好！我是你的智能编程助手 CodeGeeX。我已经仔细审查了你提供的 Git Diff 输入。下面是我对本次代码变更的详细审查意见：

变更概述

本次修改在 dde-session-daemon 的主程序中，向 treeLandNotAllowModules（TreeLand 环境下不允许加载的模块黑名单）切片中新增了 "gesture"（手势）模块。

---

审查意见

1. 语法逻辑

• 评估：语法正确，逻辑清晰。在 Go 语言中，向已有的字符串切片追加元素符合语法规范。
• 潜在逻辑风险：新增 "gesture" 到黑名单意味着当系统运行在 TreeLand 环境下时，手势模块将被禁止加载。需要确认这是否符合产品需求：
  • TreeLand 环境下是否有替代的手势管理服务？
  • 如果没有替代服务，禁用手势是否会导致用户交互体验大幅下降？
  • 建议：确保业务逻辑上确实需要在 TreeLand 下禁用手势模块，并在提交信息中说明原因。

2. 代码质量

• 评估：当前代码通过硬编码的方式维护黑名单，虽然简单直接，但在模块增多时不易维护。
• 改进建议：
  • 提取常量或配置化：如果这个黑名单经常变动，建议将其提取到配置文件（如 JSON/YAML）中，或者使用 Go 的 init() 函数或常量定义来管理，避免频繁修改主程序代码。
  • 排序与查找效率：当前切片是无序的。如果后续在代码中通过遍历切片（O(n)）来检查模块是否在黑名单中，当黑名单变长时效率不高。建议改为基于 map 的集合查找，以获得 O(1) 的查询性能。

3. 代码性能

• 评估：由于这是一个在程序启动时只初始化一次的切片，且当前元素数量极少（7个），新增一个元素对内存和初始化性能的影响微乎其微，当前无需过度优化。
• 改进建议（针对后续扩展）：如上文所述，如果后续黑名单继续增加，且在热路径中频繁调用检查函数，建议重构检查逻辑。例如：

// 重构建议：使用 map 替代 slice 以提高查找性能
var treeLandNotAllowModulesMap = map[string]bool{
    "x-event-monitor": true,
    "keybinding":      true,
    "gesture":         true, // 新增
    "screensaver":     true,
    "display":         true,
    "xsettings":       true,
    "power":           true,
}

// 检查函数可以简化为
func isModuleNotAllowedInTreeLand(moduleName string) bool {
    return treeLandNotAllowModulesMap[moduleName]
}

4. 代码安全

• 评估：本次修改仅涉及模块名称字符串的添加，不涉及用户输入、权限提升、内存操作或网络通信，无直接安全隐患。
• 间接安全考量：禁用 gesture 模块本身是一种功能降级。在某些极端场景下，如果手势模块存在与 TreeLand 不兼容的严重 Bug（如导致崩溃或死锁），将其加入黑名单反而是一种安全兜底措施，能保证系统基础稳定性。

---

总结

本次代码变更非常小且明确，语法无误，无安全风险。主要的关注点在于业务逻辑的正确性（是否真的需要在 TreeLand 下禁用手势），以及未来代码的可维护性和查询性能（建议考虑使用 map 替代 slice）。如果确认业务逻辑无误，本次修改可以合入。
