Validation

• Resolved install target with resolve-install-target.js: OpenAnonymity/oa-android.
• Confirmed GH_TOKEN was present for the install route.
• Audited source and target .github paths before copying.
• Verified .agent/dist/ and .agent/node_modules/ were not copied.
• Reviewed git status --short and git diff --cached --stat.
• Committed install diff as chore: install Sepo agent infrastructure.
• Skipped runtime test execution because this PR only copies Sepo infrastructure into the target repository.
