Add complete repository infrastructure for community launch

[jgoldfoot]

This commit adds all missing infrastructure files to prepare AgentUX for public community launch, following best practices for open source projects.

Critical Infrastructure Added

Package Management

• package.json: Full project metadata, dependencies, and npm scripts
• .gitignore: Comprehensive ignore patterns for Node.js projects
• .nvmrc: Node.js version specification (20.11.0)

Security & Documentation

• SECURITY.md: Vulnerability reporting policy and security guidelines
• CHANGELOG.md: Version history following Keep a Changelog format

GitHub Templates

• Issue templates: Bug report, feature request, documentation
• Pull request template: Comprehensive checklist for contributors
• Issue template config: Links to discussions and security policy

CI/CD Pipeline

• GitHub Actions workflows:
  • ci.yml: Test, lint, validate examples, security audit, docs check
  • pr-checks.yml: PR title validation, size checks, auto-labeling
• Labeler configuration for automatic PR labeling
• Markdown link checker configuration

Testing Infrastructure

• jest.config.js: Jest test framework configuration
• tests/: Test directory with comprehensive test suites
  • fr1-validator.test.js: FR-1 compliance testing
  • setup.test.js: Environment and structure validation

Code Quality Tools

• .eslintrc.json: ESLint configuration for code quality
• .prettierrc.json: Prettier configuration for code formatting
• .prettierignore: Prettier ignore patterns
• .editorconfig: Editor configuration for consistent formatting

Documentation Updates

• README.md: Enhanced with badges and updated development setup

What This Enables

✅ npm install now works from root directory
✅ npm test runs comprehensive test suite
✅ CI/CD pipeline will validate all PRs
✅ Clear security vulnerability reporting process
✅ Structured issue and PR templates for contributors ✅ Automated code quality checks
✅ Version management and changelog tracking

Next Steps for Launch

After this commit, the repository is ready for:

• Community contributions with proper templates
• Automated testing and validation
• npm package publication (when ready)
• Public announcement and sharing

💡 Codex Review

https://github.com/jgoldfoot/AgentUX/blob/9104034e72f47968b7192dd5ed8636a4b8a8ccdf/tools/validators/fr1-validator.js#L28-L32
Handle file URLs in FR1 validator

The validator only initializes an HTTP(S) client by doing const client = parsedUrl.protocol === 'https:' ? https : http. When a local example is passed (as recommended in AGENTS.md and in the CI workflow via file://$(pwd)/examples/...), new URL returns a file: protocol, the code still tries to use http.get, and Node throws TypeError: protocol "file:" not supported. As a result the validator cannot be run against the shipped HTML examples and the automated “Validate Examples” job must ignore failures. Consider detecting non‑HTTP(S) inputs and reading from the filesystem instead of always using http/https.
