Shuery 42f02d0eca refactor: 公共面补 BakNRet 前缀,产品名大小写全仓统一
16 个没有前缀的公共函数补上 BakNRet(Write-Log → Write-BakNRetLog、Resolve-BackupEntry →
Resolve-BakNRetBackupEntry、Find-ChildDirectoryByName → Find-BakNRetChildDirectoryByName 等),
另外把全仓的 Baknret 统一成 BakNRet(47 个文件、940 处、65 个定义文件重命名)。

这不是审美问题:静态分析直接拓出一条实据 —— Write-Log 与本机某个已装模块导出的命令
**重名**(PSAvoidOverwritingBuiltInCmdlets),而重名的后果是导入两个模块时有一方的命令被
静默遮蔽。补前缀正是这条规则的解法,改名后它归零。

为什么敢做这个规模:PowerShell 的函数名解析大小写不敏感,所以 Baknret → BakNRet 在功能
上是零风险;真正要验证的是 16 个补前缀的调用点,而 276 个断言几乎覆盖了每个函数。另外
"名字与文件名一致"这条不变式有断言盯着(加载器点源的文件集合 vs 磁盘)。

踩到并记下的坑:Windows 文件系统大小写不敏感,所以**只改大小写**的重命名会被 Move-Item
当成同一个文件而静默跳过 —— 同一批里同时改了名字的那 16 个文件却成功了,于是"看起来能跑"。
最后用"先移到临时名、再移到目标名"的两步走解决,判断与替换全部改用显式大小写敏感的形式
(-creplace / -cmatch)。

顺带把名录指纹缓存从 MD5 换成 SHA256(PSAvoidUsingBrokenHashAlgorithms):它只是缓存键,
没有兼容负担。

验收:test.ps1 9/9 全绿(7 与 5.1)、100 个文件两版解析零错、276 个断言全过、
构建工具仍能合回单文件(3300 行)。

.SYNOPSIS
把归档名对齐到当前清单规则,并重建 manifest.json。
.DESCRIPTION
归档名由清单条目决定:
* 软件名条目 -> 归档名 = 软件名(`Edge.7z`);
* 手写路径条目 -> 归档名 = `<末级名>_from_<上级路径>`(`FooClolor_from_C_+Programs.7z`)。
条目写法变过(把软件名改成手写路径、改名、合并条目……)之后,磁盘上的旧归档名就与当前
规则对不上了 —— 那样的归档恢复不到,会被当成孤儿。这个脚本负责把它们搬过去。
做法:
1. 遍历清单条目,算出**当前规则下的目标名**,以及一组**候选旧名**
(路径命名算法 / 名录里的软件名 / manifest 里记过的归档名);
2. 目标名已经存在就跳过;否则在候选旧名里找实际存在的归档;
3. 重命名(不是复制,同卷上是元数据操作,不搬数据);
4. 重建 manifest.json,把旧记录的历史字段(成功次数、SHA256 等)迁过去;
5. 比对重命名前后的文件大小做完整性自检。
默认是**试运行**,只打印计划。确认无误后加 -Apply 才真正执行。

# 默认值不能写在 param() 里:Windows PowerShell 5.1 在带 [CmdletBinding()] 的脚本上,
# 参数绑定阶段还没有给 $PSScriptRoot 赋值,默认值表达式会拿到空串(实测:带
# [CmdletBinding()] -> 空串,不带 -> 正常;PowerShell 7 两种都正常)。所以默认值
# 一律在这里补 —— 这也是本仓库对 -BackupDir / -ConfigPath 一直在用的写法。
