Slai Agent Runtime: Fix Windows Git symlink checkout

[Slai.life (huong8373tt-beep)]

Summary

This fixes Windows repository checkout for repositories that contain Git symlinks.

While validating lima-vm__lima-3351 in the SWE-bench-Live Windows subset, the base commit and the candidate both failed TestDefaultYAML. The checked-out pkg/limayaml/default.yaml contained the symlink target text:

../../templates/default.yaml

instead of resolving to templates/default.yaml. The test therefore attempted to parse the symlink target as YAML and failed before the candidate change could affect it.

Change

For Windows base-image repository setup, configure Git with:

git config --global core.symlinks true

before fetching and resetting the repository. The command is built in a small helper so the behavior is unit-testable.

Scope

• Windows checkout path only.
• No evaluator or task-source changes.
• Existing non-Windows checkout behavior is unchanged.

Validation

python -m py_compile launch/core/platforms/windows.py tests/runtime_test.py
python -m pytest -q tests/runtime_test.py -k windows_repo_clone_enables_git_symlinks
# 1 passed, 6 deselected

The motivating Lima evidence is retained locally at D:\swebench\tmp\lima3351\baseline_compare\base_limayaml.json and candidate_limayaml.json; both runs show the same symlink-text YAML failure, confirming the task candidate did not cause it.
