CarterPerez-dev 2ba81cfd82 feat(engine): typed event hierarchy + EventBus with fanout + AuditSubscriber + Engine ... Events form a Crystal class hierarchy so subscribers pattern-match exhaustively. EventBus delivers to subscribers via Crystal channels with per-subscriber overflow policy (Block for audit, Drop for best-effort). AuditSubscriber listens for all rotation/policy/drift/alert events and serializes them into the hash-chained audit log via AuditLog.append. Engine wires Persistence + AuditLog + AuditSubscriber + EventBus together so callers just .start/.stop. 7 unit specs verify boot, fanout to N subscribers, drop-on-overflow semantics, and end-to-end event -> audit row.		2026-04-29 00:47:45 -04:00
