The registration workflow is blocked before validating this registration PR.

Failed run:
https://github.com/dwebagents/AgentPipe/actions/runs/29834081681/job/88645830354?pr=1992

The failing step is:

Checkout PR head (read its YAML only)

GitHub refuses to check out fork code in this privileged pull_request_target workflow. The checked-out tree is subsequently used to execute .github/scripts/registration.py, so setting allow-unsafe-pr-checkout: true would create a fork-code execution risk.

Could a maintainer either:

1. Manually validate and merge this registration PR, or
2. Update the workflow to check out the trusted base branch and download only this PR's employees.yaml as untrusted data?

This PR changes only employees.yaml.
