1. Migration: existing users auto-seed experimental features as enabled
on first load (no feature loss on upgrade). New installs get opt-in UX.
2. Reactivity: SettingsView uses useFeatureSnapshot() so section list
updates instantly when toggles change (fixes stale useMemo deps).
3. Standards: Switch component replaces raw checkboxes, data-testid on
every toggle (feature-toggle-{id}, feature-toggle-dev-global).
4. Tests: 11 unit tests for resolveEnabled covering all tiers + edge cases.
5. Architecture: @features-manifest Vite alias replaces fragile ../../../../
relative import. Test loader also resolves the alias.
6. Versioned localStorage: keys now use -v1 suffix aligned to manifest version.
7. Cache: JSON.parse result cached across hook instances per render cycle.
8. Dev warning: console.warn in dev when getFeature() returns undefined.
