style: 按微软规范落地静态分析，并全仓机械重排

三件事： 1) tools\Install-TestDependencies.ps1 现在也把 PSScriptAnalyzer 装进仓库内的 .tools\modules （不动机器上的全局模块，与 Pester 同一策略）。 2) PSScriptAnalyzerSettings.psd1：这是必要的，不是装饰 —— 那 6 条格式规则（括号、缩进、空格、对齐、大小写）默认全是 Disabled，所以不带 -Settings 的 `Invoke-ScriptAnalyzer -Severity Warning,Error` 会**静默漏掉全部排版问题**。本文件用 Rules 把它们打开（而不是用 IncludeRules 换一套），于是默认规则与格式规则同时生效。三条有意的排除都写明了理由：PSAvoidUsingWriteHost（彩色控制台输出是这份工具的刻意设计）、 PSUseShouldProcessForStateChangingFunctions（WhatIf 的边界在入口脚本，给库里 27 个改状态的函数都加上反而会"静默跳过"，备份看着成功却什么都没做）、PSAvoidUsingPlainTextForPassword （7z 只接受命令行口令，这是 7z 的限制，README 里写明了取舍）。 3) tools\Invoke-Analyzer.ps1：独立门禁（不塞进 Pester 用例 —— 套件跑一次二十多秒，混进去会让"测试红了"这句话失去分辨力），路径过滤与验收门槛的 Encode/Parse 两层一致。全仓重排结果：706 条告警 -> 67 条。修掉的 639 条全部是格式（闭括号 168、空格 80、对齐 68、缩进 60、行长 229）。重排后 9/9 验收全绿、100 个文件两版解析零错、 276 个断言原样通过 —— 机械重排没有改变任何可观察行为。如实说明两件事： * 行长上限设成 160，**不是**官方默认的 120。120 在本仓库意味着 270 处改动（主要是中文注释与测试夹具里的一行式目录），160 意味着 41 处。160 仍是"宽但可读"，而理由是写在配置文件里的：这不是悄悄放宽，想收紧到 120 时那份清单就在分析器输出里。 * 剩余 67 条里，41 条是上面那批行长，其余 26 条是分析器找出的真问题（未使用参数 6、空 catch 6、MD5 指纹 1、覆盖内置命令 1、switch 默认值 1 等）。其中 Find-ChildDirectoryByName 的 MaxDepth 参数从未被使用 —— 也就是配置里的 CatalogMaxDepth = 5 是假的，前缀补全实际只查 1 层。这条要改行为、且影响真实名录的解析结果，留给你拍板，不在本提交里动手。
