1. Scoped token blocks cross-repo 🐞 Bug ≡ Correctness

check_merged_pr 用单仓库作用域的 APP_TOKEN 调用 /search/issues 做 org 级跨仓检索，但该 token 被显式限制仅能访问 .github 仓库，因此
search 结果将看不到其它仓库的 PR，跨仓绑定场景仍会被 T8 误判为未完成。结果是“卡在治理仓、PR 落任意仓”的问题在生产上仍可能复现。
Agent Prompt 
### Issue description
`check_merged_pr()` 新增的跨仓主通道调用了 GitHub Search API（`/search/issues`），但认证用的是 `APP_TOKEN`。该 token 由 `scripts/gh-app-token.sh` 生成，并在生成时用 `{"repositories":[".github"]}` 将 installation token 作用域限制为单仓库。这样即使 query 写了 `org:Cloudbird-Software`，search 也只能返回 token 可见仓库的 PR，无法覆盖“PR 落在其它仓库”的真实场景，导致 T8 仍可能漏判。

### Issue Context
- `scripts/gh-app-token.sh` 明确禁止不传 `REPO`，并在换 token 时传 `repositories` 参数做单仓限制。
- conductor workflow 中 `APP_TOKEN` 是用 `REPO=.github` 铸造的。

### Fix Focus Areas
- .github/workflows/conductor.yml[409-432]
- .github/workflows/conductor.yml[54-69]
- scripts/gh-app-token.sh[40-43]
- scripts/gh-app-token.sh[192-197]

### Suggested fix
1. 为跨仓 search 引入“可见范围覆盖目标仓”的凭据：
   - 方案 A：使用单独的 secret（例如 fine-grained PAT / org read token），对 Cloudbird-Software 下需要覆盖的仓库授予最小只读权限，用它调用 `/search/issues`。
   - 方案 B：调整 token 铸造策略：为 search 单独铸造一个不受 `repositories` 限制（或覆盖全部相关仓库列表）的 installation token（注意仍需满足最小权限与审计要求）。
2. 在代码中将 search 调用改为使用上述“跨仓可见”的 token，而本仓 pulls/写操作仍使用现有 `APP_TOKEN`（保持最小权限）。
3. 若无法获得跨仓可见 token，应明确降级策略并 fail-closed 给出“凭据不可见导致跨仓检索不可用”的错误提示，避免让人误以为 search 已覆盖跨仓。

跨仓检索与绑定校验仍有两个会影响合并判定的具体问题：

  1. APP_TOKEN 由 REPO=.github 铸造，只覆盖 .github；对其他私有目标仓库的 Search 无法可靠命中。请改用具备目标仓库读取权限的 installation token，或按目标仓库分别查询。
  2. check_merged_pr 及本仓回退仍使用 target in body / binding in body，会接受 Related Card: <target> 或普通句子中的提及。两条路径都应要求锚定的完整 Card: <target> 元数据行，并使用同一绑定值构造搜索条件。

complete Card metadata line for the same binding value, avoiding matches from
Related Card or inline prose, and use that identical binding value when
constructing the search query. Replace E["APP_TOKEN"] for this cross-repository
search with the configured token that has read access to the target
