Update dependencies and enhance deployment scripts

- Bumped versions of several dependencies in go.mod, including golang.org/x/crypto to v0.43.0 and golang.org/x/net to v0.46.0.
- Added new indirect dependencies for improved functionality.
- Removed outdated files: package.json, POLICY_TESTS_SUCCESS.md, and POLICY_TESTS_SUMMARY.md.
- Introduced a comprehensive deployment script for automated setup and configuration.
- Added testing scripts for deployment validation and policy system tests.
- Bumped version to v0.19.0.

+# Deployment Testing
+
+This directory contains tools for testing the ORLY deployment script to ensure it works correctly across different environments.
+
+## Test Scripts
+
+### Local Testing (Recommended)
+
+```bash
+./scripts/test-deploy-local.sh
+```
+
+This script tests the deployment functionality locally without requiring Docker. It validates:
+
+- ✅ Script help functionality
+- ✅ Required files and permissions
+- ✅ Go download URL accessibility
+- ✅ Environment file generation
+- ✅ Systemd service file creation
+- ✅ Go module configuration
+- ✅ Build capability (if Go is available)
+
+### Docker Testing
+
+```bash
+./scripts/test-deploy-docker.sh
+```
+
+This script creates a clean Ubuntu 22.04 container and tests the full deployment process. Requires Docker to be installed and accessible.
+
+If you get permission errors, try:
+```bash
+sudo ./scripts/test-deploy-docker.sh
+```
+
+Or add your user to the docker group:
+```bash
+sudo usermod -aG docker $USER
+newgrp docker
+```
+
+## Docker Files
+
+### `scripts/Dockerfile.deploy-test`
+
+A comprehensive Docker image that:
+- Starts with Ubuntu 22.04
+- Creates a non-root test user
+- Copies the project files
+- Runs extensive deployment validation tests
+- Generates a detailed test report
+
+### `.dockerignore`
+
+Optimizes Docker builds by excluding unnecessary files like:
+- Build artifacts
+- IDE files
+- Git history
+- Node modules (rebuilt during test)
+- Documentation files
+
+## Test Coverage
+
+The tests validate all aspects of the deployment script:
+
+1. **Environment Setup**
+   - Go installation detection
+   - Directory creation
+   - Environment file generation
+   - Shell configuration
+
+2. **Dependency Management**
+   - Go download URL validation
+   - Build dependency scripts
+   - Web UI build process
+
+3. **System Integration**
+   - Systemd service creation
+   - Capability setting for port 443
+   - Binary installation
+   - Security hardening
+
+4. **Error Handling**
+   - Invalid directory detection
+   - Missing file validation
+   - Permission checks
+   - Network accessibility
+
+## Usage Examples
+
+### Quick Validation
+```bash
+# Test locally (fastest)
+./scripts/test-deploy-local.sh
+
+# View the generated report
+cat deployment-test-report.txt
+```
+
+### Full Environment Testing
+```bash
+# Test in clean Docker environment
+./scripts/test-deploy-docker.sh
+
+# Test with different architectures
+docker build --platform linux/arm64 -f scripts/Dockerfile.deploy-test -t orly-deploy-test-arm64 .
+docker run --rm orly-deploy-test-arm64
+```
+
+### CI/CD Integration
+```bash
+# In your CI pipeline
+./scripts/test-deploy-local.sh || exit 1
+echo "Deployment script validation passed"
+```
+
+## Troubleshooting
+
+### Docker Permission Issues
+```bash
+# Add user to docker group
+sudo usermod -aG docker $USER
+newgrp docker
+
+# Or run with sudo
+sudo ./scripts/test-deploy-docker.sh
+```
+
+### Missing Dependencies
+```bash
+# Install curl for URL testing
+sudo apt install curl
+
+# Install Docker
+curl -fsSL https://get.docker.com -o get-docker.sh
+sudo sh get-docker.sh
+```
+
+### Build Test Failures
+The build test may be skipped if:
+- Go is not installed
+- Build dependencies are missing
+- Network is unavailable
+
+This is normal for testing environments and doesn't affect deployment validation.
+
+## Test Reports
+
+Both test scripts generate detailed reports:
+
+- **Local**: `deployment-test-report.txt`
+- **Docker**: Displayed in container output
+
+Reports include:
+- System information
+- Test results summary
+- Validation status for each component
+- Deployment readiness confirmation
+
+## Integration with Deployment
+
+These tests are designed to validate the deployment script before actual deployment:
+
+```bash
+# 1. Test the deployment script
+./scripts/test-deploy-local.sh
+
+# 2. If tests pass, deploy to production
+./scripts/deploy.sh
+
+# 3. Configure and start the service
+export ORLY_TLS_DOMAINS=relay.example.com
+sudo systemctl start orly
+```
+
+The tests ensure that the deployment script will work correctly in production environments.
