chore: align repo structure with plugin conventions

Add missing config files (.eslintrc.js, .prettierrc.js, .pluginrc,
.mcp.json, renovate.json), documentation (CLAUDE.md, CONTRIBUTING.md,
README.md, SECURITY.md, LICENSE), CI/CD workflows (ci.yaml, release.yaml),
and Claude agent definitions. Rename package from headlamp-intel-gpu-plugin
to intel-gpu to match the short-name convention used by all other plugins.
