docs(aidd-context): expand the mcp and cli guide by usage

[alexsoyes]

🎯 What & why

Expand the MCP/CLI comparison by usage so teams can choose an integration for their workflow. Add GitLab, Linear, Google Workspace, Sentry, Vercel, and Supabase, with provider provenance and support status for each route.

🛠️ How it works

Keep dashes for repeated usages and preserve the current client setup, authentication, and teardown guidance. Retain the official Notion, Playwright, and Figma CLI routes already on next; distinguish Google's unsupported gws project and GitLab's experimental MCP from ordinary official routes.

🧪 How to verify

• Review the table and linked provider documentation in mcp-installation.md:26.
• git diff --check passed; commit hooks run the recipe validator and repository checks.

✅ I certify

• I DO CERTIFY I READ EACH LINE OF THE PULL REQUEST BECAUSE I AM A SOFTWARE ENGINEER, NOT A AI PUPPY.
