Log DDL as well

Having implemented a script/bootstrap setup for project that creates a database, migrates through various migrations, inserting a few rows here and there, black.water shines very well on the SQL output. However, it would be great if it also output DDL transformations. This is particularly nice for boxen (but also production) setups where any failure automatically opens a ticket on github with the output. Some example code where it would be nice:

```
(ns example.migrations.v0
(:require [clojure.java.jdbc :as j]
[clojure.java.jdbc.sql :as sql]
[clojure.java.jdbc.ddl :as ddl]
[example.db :as db]))

(defn create-metadata-table! [db-conn]
(j/db-do-commands db-conn
(ddl/create-table
:metadata
[:schema_version "integer"]))
(j/insert! db-conn :metadata {:schema_version 0}))

(defn migrate! [db-conn]
(create-metadata-table! db-conn))
```

The only black.water output from the above will be: `INSERT INTO metadata ( schema_version ) VALUES ( ? ) | 0| took:11ms`

Start by tracing black.water's existing SQL output around the example's j/db-do-commands call and INSERT logging path. Identify the entry point that observes JDBC commands, then verify that DDL statements are emitted alongside INSERT output without changing migration behavior; no test file is named in the issue.
