wip: Fix example server TypeScript errors

- Fix Event type imports (use EventType enum, RunErrorEvent type)
- Update Express type definitions
- Configure tsx for runtime TypeScript execution
- Add esbuild to workspace root

The example server still needs workspace configuration to run properly.
The core integration builds and exports correctly.

Status:
✅ Core integration builds successfully
✅ TypeScript errors fixed in example code
⚠️ Example server needs pnpm workspace integration
⚠️ Server-starter pattern or mastra examples pattern needed
