Simplify ArtifactsRuntimeProvider constructor

- Take artifactsPanel and agent directly instead of 5 separate function parameters
- Define minimal ArtifactsPanelLike and AgentLike interfaces to avoid circular deps
- Update all call sites (ChatPanel, browser-javascript) to use simplified constructor
- Much cleaner and easier to use
