Comprehensive Testing Suite Implementation

[codedbytahir]

This PR introduces a robust and comprehensive testing framework for the MotionForge project, covering multiple levels of the stack:

1. Unit Testing (Core Library): New tests in packages/motionforge/src/__tests__ verify the logic of the PlayerEmitter, canvas transformation utilities, asset preloading, and component visibility logic.
2. Integration Testing (Renderer & CLI):
   • packages/motionforge-renderer/src/__tests__ ensures the resource pool correctly manages concurrent browser pages.
   • packages/motionforge-cli/src/__tests__ verifies CLI command resolution and cross-package dependencies.
3. End-to-End Testing (Playwright):
   • player-interaction.spec.ts: Verifies real-world user actions like play/pause and seeking on the interactive demo.
   • cinematic-scenarios.spec.ts: Ensures complex WebGL-based compositions render correctly.
   • studio-ui.spec.ts: Validates basic visibility of the studio infrastructure.
4. DevX & Hygiene:
   • Unified bun run test command triggers both unit and E2E suites.
   • .gitignore updated to prevent accidental commitment of reports, screenshots, and build artifacts (dist/).
   • playwright.config.ts now automatically manages the dev server during E2E runs.

All tests passed successfully in the local environment.
