- phase3.go: RequestExecution now calls InsertEntity before InsertExecution
(executions.entity_id references entities.id via FK constraint).
- mcp/server.go: request_execution MCP tool same fix — inserts entities row
with slug 'exec:<target>:<id8>' before executions insert.
- docker-compose.yml: fix seed OIKOS_SEEDS_DIR from /app/seeds to /seeds
(distroless image COPY destination).
