chore(docker): add local Postgres/MinIO/Qdrant compose stack

docker-compose.yml

+# Application-owned local infrastructure: Postgres, MinIO, Qdrant.
+#
+# Intentionally separate from docker-compose.langfuse.yml (different service
+# names, volumes, and ports). Run alone for app development, or combine with
+# Langfuse:
+#
+#   docker compose \
+#     -f docker-compose.yml \
+#     -f docker-compose.langfuse.yml \
+#     --env-file .env \
+#     --env-file .env.langfuse \
+#     up -d
+#
+# Do not use this compose stack as-is for production.
