Play Policy Insights: data safety, login credentials, and restricted permissions

You must audit Android apps for three specific policy domains. You must check data safety, demo login credentials, and restricted permissions.

Path Resolution

repo_root: Absolute path to the directory containing this SKILL.md.
app_dir:: Absolute path to the directory containing app's code.
temp_dir: Absolute path to the scratch directory at the workspace root. It is located at .scratch/play_policy_insights_<uuid>. Containment Mandate: You must confine all file system writes, intermediate artifacts, and logs strictly to this directory. This ensures the skill remains portable and safe across diverse execution environments, including local harnesses and CI/CD pipelines, by avoiding reliance on system-level temporary paths or user home directories.
