Previous fix injected base target=_top but the sandbox attribute lacked allow-top-navigation, so the browser blocked link clicks and the user had to Ctrl+Click as a workaround. Fix: sandbox allow-same-origin allow-popups + base target=_blank. Links now open in new tab (better UX, no content loss). Also fix deploy/rebuild.ps1 to read jar from target/ instead of deleted deploy/baota/. Add agent_test/ scripts: create_7_test_projects, upload_test_html, manual_package.
