feat(p8): reminders (sandbox + inbox) + CalendarProjector (AI-event auto-bridge)

Task 8.4: schedule queues one sandbox reminder (OutboundService) + a SYSTEM_ALERT
inbox item per participant, idempotent (outbound key + per-meeting marker) +
meetingReminderQueued event. CalendarProjector consumes aiArtifactAccepted → for
each EVENT claim proposes a meeting_request (PROPOSED, sourceClaimId), idempotent
via claim() + per-claim dedup. 2 tests: reminder replay-safe, AI-event→request once.
