What changed in this PR

This pull request adds a mediator service that enables mods to publish and subscribe to strongly typed events through the StarMap API.

Changes:

• Registers mediator and mediation services with dependency injection.
• Implements publisher registration, subscriptions, disposal, and sequential or parallel publishing.
• Exposes public mediation interfaces and event contracts.
• GetPublisher currently registers a new publisher on every call, preventing repeated access for the same event type; its behavior or naming should be corrected.
