InboxService.list (fail-closed) + transition (OPEN/SNOOZED/DONE/STALE/ARCHIVED
state machine, owner-only, state-history). GET /v1/inbox/items + PATCH
/v1/inbox/items/:id. Moved SessionVerifier to global IdentityModule (shared by
message + inbox, no circular imports). 35 tests green.

Event-driven projector creates/collapses NEEDS_REPLY items from message.sent
(traceId propagated; inbox.item.created emitted) and resolves them to DONE on
message.read; idempotent via processed-event ledger. markRead now emits a
message.read outbox event (atomic). OutboxRelay runs on a 500ms timer in the
app (off in tests). Shared resetDb (TRUNCATE CASCADE) fixes cross-spec FK
isolation. 32 tests green.
