_⚠️ Potential issue_ | _🟠 Major_

**Add required type hints + Google‑style docstrings for fixture and test methods.**

The `runner` fixture (Line 19) and public tests lack type hints and the required docstring sections. Please update across this file.

<summary>✅ Example pattern (apply broadly)</summary>

```diff
-@pytest.fixture
-def runner():
-    return CliRunner()
+@pytest.fixture
+def runner() -> CliRunner:
+    """Provide a Click CLI runner for tests.
+
+    Args:
+        None.
+    Returns:
+        CliRunner: Isolated CLI runner.
+    Cost:
+        $0.00 (CLI help only).
+    Example:
+        runner.invoke(cli, ["--help"])
+    """
+    return CliRunner()
```
</details>

As per coding guidelines, “All public methods in generator classes and test files must include type hints for parameters and return values” and “Write docstrings for every function using Google style format” and “All public methods should include docstrings with Args, Returns, Cost information, and Example sections”.

```
In `@tests/test_click_app.py` around lines 19 - 220, Add explicit type hints and
Google-style docstrings (including Args, Returns, Cost, Example sections) to the
runner fixture and all public test functions/methods in this file (e.g., the
runner fixture, TestRootGroup methods, TestVimaxSubgroup methods,
TestCommandHelp.test_command_help, all TestRequiredOptions methods,
TestSetupPyVimax.test_vimax_not_in_console_scripts, and TestPyInstallerSpec
methods). For each function/method add parameter and return type annotations
(e.g., runner: CliRunner -> CliRunner or -> None for tests) and a docstring
following Google style that documents Args, Returns, Cost, and provides a short
Example; import any needed types (e.g., CliRunner from click.testing or typing
types) at the top of the file. Ensure every public test method and the fixture
include both the type hints and the required docstring sections.
