Bindings for Event Sourcing and CQRS capabilities in Dapr applications
summary
A custom Dapr component implements command/event/query routing to an external event store, exposing operations to read prior events and append new events for true event sourcing, register handlers, and send commands or queries. It proxies to an Axon-compatible backend over gRPC, offers location transparency with a local command bus fallback for collocated handlers, and plans language-specific developer helpers for dispatching and projection updates. Work in progress but already functional.
