Go CI fails on golangci-lint's gofmt check. Ran gofmt -w against
every file the linter named plus a handful of others that drifted
during the autonomous-fleet work. No semantic changes — alignment
of struct field whitespace and one mis-indented import block.
gofmt -l ./... is now empty; go build + go vet are clean.
Transport-agnostic EventBus (Publish / Subscribe / Close / Name) with
two implementations:
KafkaBus - wraps the existing internal/infrastructure/kafka producer
and consumer. Existing call sites that use the kafka
package directly keep working.
NATSBus - JetStream-backed. File storage, 7d max age, durable
consumers per group, manual ack with redelivery on
handler error.
Factory FromEnv selects via EVENTBUS_PROVIDER (default kafka). NATS
needs NATS_URL; Kafka reuses the existing bootstrap+SASL config.
Subject naming converts Kafka colons to NATS dots so the existing
w:<uuid> topic naming works on both backends.
16 tests including round-trip ack-redelivery against an embedded
nats-server.
