Launching the app died with "'dict' object has no attribute 'readiness'".
TeamView.__init__ forwarded its legacy app_state dict into update_data(snapshot),
whose guard only handled None, so {} reached snapshot.readiness. TeamView is the
default view, so the window never appeared.
Fixes the call site and hardens every snapshot guard to fall back on anything
that is not a HubSnapshot. Adds tests/test_view_startup_contract.py, which
checks both conditions statically and therefore runs headless; verified to fail
on the pre-fix sources.
The GUI-import invariant previously matched the literal string "customtkinter",
which missed modules pulling it transitively. Rewritten over the AST, it
immediately found test_codex_opencode_wizard.py importing router.ui.components
without pytest.importorskip — the same defect that took the release gate down
once before, hidden until now behind conftest's name-based skip.
