fix: Adapt SQL queries to actual Outline database schema

- Users: Use role enum instead of isAdmin/isViewer/isSuspended booleans
- Users: Remove non-existent username column
- Groups: Fix group_users table (no deletedAt, composite PK)
- Attachments: Remove url and deletedAt columns, use hard delete

All 10/10 core queries now pass validation.

+## [1.0.1] - 2026-01-31
+
+### Fixed
+
+- **Users:** Adapted to Outline schema - use `role` enum instead of `isAdmin`/`isViewer`/`isSuspended` booleans
+- **Users:** Removed non-existent `username` column
+- **Groups:** Fixed `group_users` table queries - no `deletedAt` column, composite PK
+- **Groups:** Fixed ambiguous column references in subqueries
+- **Attachments:** Removed non-existent `url` and `deletedAt` columns
+- **Attachments:** Changed delete to hard delete (no soft delete support)
+
+### Changed
+
+- Users suspend/activate now use `suspendedAt` column instead of boolean
+- Groups member count uses correct join without deletedAt filter
+
 ## [1.0.0] - 2026-01-31
