## 📝 Summary of Changes

1.  **Database Security (`firestore.rules`)**
    - Updated `documents` collection rules to allow read/write based on `visibility` field.
    - Added `isPublic()` helper function: Checks for `visibility == 'public'` or legacy data (missing field).
    - Enforced strict ownership for `dailyNotes` collection.

2.  **Application Logic**
    - **Types**: Updated `Visibility` type to `'public' | 'private'`.
    - **New Documents**: Default visibility set to `'public'` for Wiki, `'private'` for Daily Notes.
    - **List Filtering**: Updated `fetchDocuments` and `HubDocuments` to filter out private documents authored by others.

3.  **User Interface**
    - **Editor Header**: Added a togglable visibility button (🌏 Team / 🔒 Private) visible only to the author.
    - **Search Modal**: Updated filter logic to respect visibility settings.
