refactor(editor): infer Monaco types from public APIs

Replace direct monaco-editor type imports in AgentEditor with
types inferred from OnMount and setModelMarkers.

This reduces coupling to Monaco internals and keeps the editor
typed against the APIs already used by @monaco-editor/react.refactor(editor): infer Monaco types from public APIs
