AA-302: Add Rook coding-agent and CI/CD integration guides

[4DvAnCeBoY]

Summary

Addresses AA-302: document Rook setup with coding agents and integration with CI/CD workflows.

• Add a coding-agent hub and separate guides for Claude Code, Codex CLI, Gemini CLI, GitHub Copilot CLI, OpenCode, Cursor CLI, Antigravity CLI, VS Code with Copilot, Windsurf Cascade, and Antigravity IDE.
• Use the public LambdaTest/rook skill bundle. Clearly distinguish the three explicit npm-installer targets from standards-based, manual project installations for the other clients.
• Add dedicated GitHub Actions, Jenkins, and Argo CD guides with downloadable workflow, Jenkinsfile, Dockerfile, Kubernetes Job, and shared reviewed-suite gate script.
• Document credentials, scoped permissions, credit spending, strict verdict gating, failure evidence retention, and Argo CD PostSync limitations.
• Add Coding Agents & Skills and CI/CD Integrations beneath Agent Assurance Platform → Autonomous Agent Testing; link existing installation, quickstart, CI/CD, and Agent Skills pages to the new guides.
• Reuse page-only local and hosted Rook result screenshots, explicitly labelled as illustrative smoke-test evidence rather than client/platform-specific execution captures. Hosted links use https://rook.lambdatest.com/projects.
• Preserve working static-download URLs in both rendered pages and generated Markdown exports.

Validation

• node --test scripts/rook-docs.test.cjs: 31 passed, covering page metadata/navigation, images and links, downloadable/example consistency, YAML safeguards, Bash syntax, Markdown export fidelity, successful/failed/incomplete/malformed/stale result gating, and Antigravity full-bundle copying/non-overwrite safeguards.

• bash -n static/resources/rook/rook-ci.sh and git diff --check: passed.

• Published Rook CLI 0.1.3 version and relevant help checked in isolation, without replacing the existing local development binary.

• Published skill installer 0.1.0 install, update, and uninstall checked for all three packaged clients in a temporary prefix; personal skills were not changed.

• All thirteen client/platform pages and the hub inspected locally with Vercel agent-browser; desktop rendering and 390px mobile layout checked. Static download links verified with HTTP 200 responses. The two Antigravity guides were also checked against the locally served production build.

• Production Docusaurus build passed using local-only placeholder Typesense settings (HOST=127.0.0.1, API=local-build-placeholder) because this checkout has no search-service configuration. No environment configuration was committed. Existing unrelated duplicate-route, CSS, and broken-anchor warnings remain.

• Antigravity setup cross-checked against Google's official CLI/IDE/skills documentation. Installed agy 1.1.2 version/help checked; the pinned public Rook skill was copied in an isolated temporary repository, all seven references verified, and a repeated install safely refused. No personal skills were changed.

Scope and limitations

• Documentation and downloadable reference examples only; no production application, Rook installer, or active repository CI workflow is changed.
• No paid Rook test, live GitHub Actions/Jenkins job, Argo CD deployment, live Antigravity-driven evaluation, or live search-service validation was performed.
• The examples deliberately use a strict release policy for Unable to Verify and other evidence gaps; the difference from the public skill's more permissive CI recipe is documented.
• Argo CD's PostSync verification does not automatically roll back a deployment, and selective sync bypasses hooks.
