==================

This PR resolves a circular dependency issue in Excalibur.js when using TypeScript source files directly. It refactors ParticleEmitter by isolating it into a separate file and adjusting the dependency management in Particles.ts.

This PR has the advantage that you should not encounter this problem if Webpack should ever be replaced.

Closes #3055

Changes

• Isolated ParticleEmitter: Moved ParticleEmitter to its own file to manage dependencies more effectively.
• Updated Particles.ts: Replaced direct dependency with a type import of ParticleEmitter.
• Instance Check Adjustment: Replaced the instanceof check with a constructor presence check.
