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.
- Introduced new agents: gem-chrome-tester, gem-devops, gem-documentation-writer, gem-implementer, gem-orchestrator, gem-planner, gem-researcher, and gem-reviewer.
- Updated README.collections.md to include the new Gem Team Multi-Agent Orchestration collection.
- Created gem-team.collection.yml and gem-team.md for structured documentation of the multi-agent orchestration framework.
- Each agent includes detailed descriptions, workflows, operating rules, and final anchors for clarity on their functionalities and usage.
