feat(service): outbox relay + thread read endpoint + replay (P1.5, P1 complete)

OutboxRelay: FOR UPDATE SKIP LOCKED claim, in-process bus publish, PENDING-> PUBLISHED with 30s backoff + idempotent-consumer ledger. GET /v1/threads/:id/ messages (policy-scoped). Replay + read specs green; vitest fileParallelism off (shared DB). End-to-end HTTP smoke verified: idempotent ingest, read-back, 400 on missing key. 19 tests pass.
