#16 Notification privacy controls: mute all + hide message preview

Notification privacy controls

Carrier already bridges the page's Web Notification API to native OS notifications (notificationBridge in src-tauri/inject/messenger.js), but there's no way to mute them or hide the message body. Caprine offers both. Add two settings:

1. Mute all notifications (master toggle)

• New setting (default off) — e.g. mute_notifications.
• When on, the bridge suppresses native notifications entirely (the unread badge / auto-refresh still work).
• This is a genuine gap — Carrier currently has no master mute.

2. Hide message preview

• New setting (default off) — e.g. hide_notification_preview.
• When on, native notifications show a generic title/body (e.g. "Messenger" / "New message") instead of the sender name and message text.

Implementation notes

• Both are tiny changes inside the existing CarrierNotification shim in messenger.js:
• Mute → early-return before calling plugin:notification|notify (still call __carrierOnNotification so auto-refresh keeps working).
• Hide preview → replace title/options.body with the generic strings before notifying.
• Read both from window.__CARRIER_SETTINGS__; they already update live via carrier:settings.
• Add to the Settings struct (src-tauri/src/lib.rs) and the Settings window (dist/settings.html).

Part of the Caprine privacy-parity set.

Done — implemented in [#21] (merged to main).

Settings → Notifications now has:

• Mute Notifications — suppress all new-message desktop notifications (the background auto-refresh still runs, so a backgrounded window keeps catching up).
• Hide Message Preview — notify with a generic "Messenger" / "New message" instead of the sender name and text, and drop the avatar so the sender isn't shown.

Both apply live from the Settings window (no restart).
