viyatb-oai b1ccaa0e08 Avoid overwriting symlinked migration targets (#36051) ...

## Why

External-agent migration treated symlinked empty text targets as overwritable files. Writing migrated configuration through such a target could modify a file outside the repository.

## What changed

- Use symlink metadata when checking whether a migration target is missing or empty, so only regular files are considered overwritable.
- Preserve symlinked `AGENTS.md` and `.codex/hooks.json` targets during both detection and import.

## Testing

Added Unix regression coverage for existing and dangling symlink targets for both guidance and hooks migration.
