🧪 Comprehensive Testing Infrastructure & Bug Fixes

This PR introduces a complete testing framework for pp-dev along with critical bug fixes and CI/CD improvements.

---

🔧 Bug Fixes

• fix(plugin): Move topbar scripts injection to head-prepend for earlier page lifecycle loading (a248f91)
  • Moves auth/info.js, main.js, and main.css from body to head-prepend
  • Ensures toolbar assets load before page content renders

---

🧪 Testing Infrastructure

Unit & Integration Tests (Vitest)

• Add comprehensive unit tests for:
  • Config loading and validation
  • Formatting helpers (html, css, templateFunction)
  • Color helper utilities
  • URL helper functions
  • Plugin normalization
• Add integration tests for middleware:
  • pp-redirect middleware
  • proxy-cache middleware
  • rewrite-response middleware

E2E Tests (Playwright)

• Add toolbar E2E tests:
  • Visibility and positioning
  • Minimize/expand functionality
  • Popup interactions
  • Sync button behavior
• Add config watcher tests:
  • Debounce behavior verification
  • Config reload functionality

Test Scripts

• npm run test:unit - Run unit tests
• npm run test:integration - Run integration tests
• npm run test:e2e - Run E2E tests
• npm run test:all - Run all tests
• npm run test:unit:coverage - Run with coverage

---

🐳 Docker Testing Environment

• Add Dockerfile and .dockerignore for containerized test execution
• Add run-tests.sh script for running dev servers in Docker
• Support for CommonJS, Next.js ESM, and Next.js CJS test projects

---

⚙️ CI/CD Improvements

• ci: Restore push trigger for develop branch in CI workflow (7a3bb34)
  • Ensures CI runs on direct pushes, not just PRs
  • Prevents untested code from being released via beta workflow
• ci: Add @semantic-release/npm plugin with npmPublish: false (ac02ca4)
  • Updates package.json version during release without npm publish

---

🧹 Maintenance

• Update test project dependency paths to correct relative location
• Add test dependencies: vitest, @vitest/coverage-v8, @playwright/test, yargs
