Remove "detailed thinking on" directive and consolidate operating_rules sections for consistency. Both gem-browser-tester.agent.md and gem-devops.agent.md now share standardized rules: unified tool activation phrasing ("Always activate tools before use"), merged context-efficient reading instructions, and removed agent-specific variations. This simplifies maintenance and ensures consistent behavior across different agent types while preserving core functionality like evidence storage, error handling, and output constraints.
Rename the Chrome-specific testing agent to a browser-agnostic version
to support multiple automation tools (Playwright, Chrome DevTools, etc.).
Updates all references in orchestrator and planner configurations, and
broadens the description and execution workflow to be tool-flexible.
Evidence storage rule clarified to apply primarily on failures.
