"""
Live-GUI smoke test for the tkinter.filedialog AttributeError regression.

On Python installs where the Tcl/Tk runtime is missing, the lazy
`tkinter.filedialog` import raises AttributeError, which previously
crashed the Project Settings window and the Add Project button.
The unit-level test in `test_lazymodule_filedialog_fallback.py`
deterministically exercises the fallback path; this live test verifies
the same fix in the actual running app: opening the Project Settings
window via the Hook API must not produce an AttributeError, and the
app must remain responsive (proving no crash on attribute resolution).

 """
 Regression: the Project Settings window's render call chain ends
 in `render_projects_panel` → `filedialog.askopenfilename(...)` on
 the "Add Project" click frame. Before the fix, every frame the
 Project Settings window was open on a broken tkinter install would
 log `AttributeError: module 'tkinter' has no attribute 'filedialog'`.
 The fix in `_LazyModule._resolve()` falls back to a `_FiledialogStub`
 that returns empty strings.

 This test:
 1. Opens the Project Settings window via the Hook API
 2. Waits several render frames
 3. Verifies the window opened (state is reflected back via get_value)
 4. Verifies the app is still responsive (status endpoint returns 200)
 5. Verifies no AttributeError was logged (the bug would print to
    the GUI's stderr, which the live_gui fixture captures to a log)
