The redesigned views are pure renderers: update_data returns early instead of
falling back to HubStateStore. That made the guard check skip for all nine
views, so the invariant silently stopped protecting the crash it was written
for. The store-access precondition is dropped; the isinstance guard is asserted
either way.

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.
