`--sql` flag does not generate SQL profile

Generating with `--sql` produces no `:db.sql/*` keys in `system.edn`, and `resources/queries.sql` / `resources/migrations/placeholder.txt` are missing.

```bash
neil new io.github.kit-clj/kit myapp --sql
```

`--conman --migratus` works as a workaround.

Cause: in `libs/deps-template/src/io/github/kit_clj/deps_template.clj`, `excluded-template-files` only checks `:conman` / `:migratus`, and the `system.edn` Selmer template only branches on `conman?` / `migratus?` / `hikari?`. Nothing maps `:sql` to those, so passing only `--sql` leaves all SQL components disabled.

Versions: `deps-template` 0.1.89.

Start in libs/deps-template/src/io/github/kit_clj/deps_template.clj and inspect excluded-template-files, then read the system.edn Selmer template branches for conman?, migratus?, and hikari?. Run `neil new io.github.kit-clj/kit myapp --sql`; done means system.edn contains the :db.sql/* keys and the expected resources/queries.sql and resources/migrations/placeholder.txt files are generated.
