ServiceBuilder

The contract-driven service builder.

Built by hoppity.service(), supports .use(middleware) chaining and .build() to produce a wired ServiceBroker.

Build phases when .build() is called:

Derive topology from handlers + publishes
Merge with optional raw topology (raw is base, derived layers on top)
Run middleware pipeline (they see the complete topology)
Create Rascal broker via BrokerAsPromised.create()
Wire event/command/rpc handlers (subscribe to queues, wrap with interceptors)
Wire outbound methods (publishEvent, sendCommand, request, cancelRequest — wrap with interceptors)
Run middleware onBrokerCreated callbacks (they see the fully-wired broker)
