Pull request overview

This PR updates Avocado’s command execution helper and its usage sites to prefer child_process.execFile() over exec(), aiming to avoid shell-string execution and improve argument handling.

Changes:

• Replace the internal child-process wrapper from exec() to execFile() and update call sites (git runner + test).
• Bump package version to 0.10.6 and add a check script to run build/test/lint/format checks.
• Document the change in CHANGELOG.md.
