fix(update): normalize version strings for correct comparison

The version check was comparing "4.0.8" (no prefix) with "v4.0.8"
(with prefix), causing it to always think an update was available.

Now both versions are normalized to have the "v" prefix before
comparison, so "Already up to date!" works correctly.
