fix: 移除误提交的 agent-registry gitlink，修复 gate/scorecard checkout 失败

[randypanding]

改了什么

• 删除仓库索引中的 agent-registry gitlink（mode 160000，无对应 .gitmodules）

为什么

• 初始提交 416f5f5 将 agent-registry 以 gitlink 形式带入仓库树，但本仓没有 .gitmodules
• actions/checkout 在 "Removing auth" 阶段执行 git submodule foreach 时报 fatal: No url found for submodule path 'agent-registry' in .gitmodules，导致 gate 与 scorecard 在 main push 及全部 PR 上一律失败（含 feat: event.schema v1.1——补 6 类治理审计事件（ADR-0016） #47–fix: governance-drift 评论按漂移指纹去重（红队 RB-B2，ADR-0016） #51 共 5 个 open PR）
• REPOS.yaml 头部注释明确本组织采用「替代 submodule 方案：无指针过期、无 recursive clone 问题」，gitlink 属于误提交残留
• 变更路径为仓库根（非 C1 路径），不涉及治理文件

怎么验证

• 本 PR 的 gate workflow 将首次通过 checkout 阶段（此前所有 PR 均失败于 checkout）
• git ls-tree HEAD 确认仅删除 gitlink 条目，无文件内容变更
• 合并后重触发 feat: event.schema v1.1——补 6 类治理审计事件（ADR-0016） #47–fix: governance-drift 评论按漂移指纹去重（红队 RB-B2，ADR-0016） #51 的 gate 验证恢复

风险 / 回滚

• 极低：纯索引条目删除，无内容变更；如需回滚 revert 即可

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.

Remove accidental agent-registry gitlink to restore CI checkout

🐞 Bug fix ⚙️ Configuration changes 🕐 Less than 5 minutes

AI Description

• Removes the unconfigured agent-registry gitlink from the repository index.
• Prevents submodule cleanup errors from blocking gate and scorecard workflows.
• Aligns repository structure with the organization’s non-submodule strategy.

High-Level Assessment

Removing the orphaned gitlink is the optimal approach because the repository intentionally avoids submodules and has no .gitmodules configuration. Adding submodule metadata would preserve an unintended dependency and conflict with the documented repository strategy.
