Summary

Create a demonstration application within this repository that showcases EventCore's capabilities with PostgreSQL as the event store backend.

Motivation

A working demo application would:

Serve as a practical reference for users integrating EventCore
Demonstrate best practices for event sourcing patterns
Provide a testbed for validating the library's ergonomics
Help identify API friction points before they become entrenched

Suggested Scope

Simple domain (e.g., bank account, todo list, inventory)
Full event sourcing lifecycle: commands, events, projections
PostgreSQL event store configuration
Example read models / projectors
Docker Compose setup for easy local running

Acceptance Criteria

Demo application compiles and runs
README with setup instructions
Demonstrates at least 2-3 aggregate types
Shows projection/read model patterns
Includes integration tests as usage examples
