### Added
- **Extra BitTorrent Bootstraps** picker in Settings → Network Details — lets the user supply additional BitTorrent bootstrap nodes so Ouinet can connect on networks where the default bootstraps are blocked; new `BootstrapPickerView` in `CenoUI` backed by `BootstrapState` in `CenoCore`
- `ExtraBootstrapEnvironment` / `OuinetBootstrapEnvironment` and a `BootstrapProperties.template.plist` resource holding the default bootstrap configuration
- `RemoveSavedOuinetConfIntentProd` — intent that clears the saved Ouinet conf file

### Changed
- Extra bootstraps are now applied via `OuinetConfig` (rather than posted as sources), with the previously saved conf cleared on apply
- Applying extra bootstraps restarts the Ouinet client from the Bootstrap picker so the change takes effect immediately
- Sentry debug logging disabled to reduce log noise

### Changed
- Adopted unidirectional data flow (MVI/TCA): a single `ApplicationState` root
holding `@Observable` states replaces the ViewModel layer as the source of truth for the entire UI,
injected into the SwiftUI environment at the scene boundary
- All side effects (browser, bookmark, ouinet, cache operations) are now expressed
as named intents dispatched through `IntentLibrary`, with explicit production
implementations

### Added
- Add toggle for bridge mode in Ceno iOS

### Fixed
- Granular cache-clearing UI — new sheet lets the user choose between clearing
cache only or clearing cache and all app data, replacing the previous
single-option alert
- Opens a new public tab via top-level application intent
- Clear Ceno via top-level application intent
- Show blank URL in address bar when a new tab selected

### Removed
- `BrowserViewModel`, `HomeViewModel`, `BrowserToolbarViewModel`, `SceneViewModel`
— superseded by State/Intent layer
- `BrowserToolbarDelegate` — replaced by Intent dispatch
