Subject: [PATCH] test: add unit test for Config::get_submodule

This commit adds a new test case `test_config_get_submodule` to
`src/config.rs`. The test verifies that `Config::get_submodule`
correctly retrieves a submodule entry when it exists and returns
`None` when it does not.

Gaps addressed:
- Missing test for `Config::get_submodule`

Coverage:
- Happy path: retrieving an existing submodule.
- Edge case: attempting to retrieve a non-existent submodule.
