feat: 重构被审查分支的选择逻辑

push 审查
  check_branches 现在只表示「要做 push 审查的分支」，不再兼作 PR 目标分支：
  - 勾选具体分支：这些分支的 push 会审查，通过后晋级到管理分支
  - 新增「任意分支」(*)：所有分支的 push 都审查
  - 留空：只审 PR，不审 push

PR 审查
  始终覆盖「勾选的分支 + 管理分支」作为合并目标。
  管理分支是最终目标，不需要出现在检查分支里也能被保护。

管理分支从候选中移除
  分支选择器不再列出管理分支——它是终点，不需要再检查自己。

安全边界
  「任意分支」只扩大审查范围，不会把任意分支自动合并进管理分支；
  晋级仍要求分支被显式勾选（promotesToManaged）。

同时修正一处语义错误
  早先 branchMatches 把空列表当成「审所有分支」，导致新建仓库在用户
  还没选分支时就审查全部 push。现在空列表明确表示「只审 PR」。

测试：分支匹配矩阵重写，覆盖 push/PR/晋级/保护目标四类判定，共 20 项通过。

-**分支与合并**：`check_branches` 是**被保护的目标分支**。任何合并进这些分支的 PR 都会被审查，所以功能分支不必列进去；向这些分支直接推送也会审查。审查基准是该改动实际要合入的分支（PR 用 PR 自己的目标分支，push 用管理分支），也就是「这次改动合进去会怎样」。

+**PR 审查**始终覆盖「勾选的分支 + 管理分支」作为合并目标，所以管理分支不需要出现在检查列表里。审查基准是该 PR 实际要合入的分支。
 
 自动合并作用于目标为**任一检查分支**的 PR，因此两级流转可以直接用：
