All 5 projectors (route/ai/inbox/calendar/raw-event) now advance their
IiosProjectionCursor after a freshly-claimed event is applied — split into
claim → apply → advance so a duplicate never double-counts and a throw leaves
the cursor untouched (event replays via the DLQ). Inbox's two topics get two
cursor rows. Proves KG-06 replay reproduction at the projection level.

Projectors register a replay handler and route bus errors to
dlq.onConsumerFailure (dead-letter + clear the claim-then-fail claim)
instead of swallowing them. Relay dead-letters an outbox event after
IIOS_OUTBOX_MAX_ATTEMPTS instead of retrying forever. Chaos test proves
poison → DLQ → replay resolves while sibling events keep flowing (KG-13/KG-06).
