chore: replace legacy type comment in test_exceptions

bdraco · bdraco · commit bc5e1878a185 · 2026-05-15T11:34:51.000-07:00
mypy 2.0 (pulled in by the pre-commit autoupdate) rejects the
old `browser = None  # type: Zeroconf` form because None is not
assignable to Zeroconf. Switch to a class-level annotation
without an initializer; setUpClass assigns the real value before
any test runs.
