Preview Testing

Preview testing skill for Lovable projects. Activates when: - preview_testing: on in CLAUDE.md - Running /lovable:test-init, /lovable:test-run, or /lovable:test-sync commands - After implementing a new feature when test plans exist (suggest test updates) - After auto-deploy completes when test_after_deploy: on - Any mention of "test in preview", "preview testing", "test plans", "e2e tests in Lovable" Tests the running app in Lovable Preview mode via browser automation. Manages standardized test plans, test profiles, and results in .lovable-agent/tests/ while preserving .claude/lovable-claude/test/ as a backward-compatible alias. Keeps test plans in sync with the codebase…
