Set up CI/CD pipeline with GitHub Actions

[coderooz]

Status: Pending

What

Complete CI/CD pipeline for the monorepo:

CI (on push/PR):

• TypeScript type checking (tsc --noEmit)
• Lint (eslint via expo)
• Test (vitest for core + feature packages)
• Build (all workspace packages + bundle assets)
• Verify bundle output matches expected structure

CD (on release/tag):

• Build all packages
• Publish to npm (expo-template-coderooz, @coderooz/core, @coderooz/create-app, @coderooz/cli)
• Create GitHub Release with changelog

Existing files:

• .github/workflows/ci.yml — needs update
• .github/workflows/release.yml — created but untested
• .github/workflows/security.yml — created but untested
