feat(ios): Live Activity for running queries and iPad multi-window support

CHANGELOG.md

@@ -9,13 +9,15 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ### Added
 
+- iOS: Live Activity for running queries shows query preview, elapsed time, and row count on the lock screen and Dynamic Island
+- iOS: multi-window support on iPad - drag a tab off to open a second window, each window remembers its own selected connection across launches
 - iOS: VoiceOver "Delete row" / "Delete group" / "Delete tag" custom actions on rows whose only deletion path was a swipe gesture
 - iOS: empty Groups and Tags screens show a Create button so the action is reachable without opening the toolbar
 - iOS: "No Results" empty state in Query Editor explains the query returned no rows
 - iOS: iCloud sync runs every 30 minutes in the background via `BGAppRefreshTask` while the app is closed (gated by the iCloud Sync setting); iOS schedules the actual cadence based on usage and battery
 - iOS: Cmd+F focuses the search field in Tables and Data Browser (iPad keyboard canonical)
 - iOS: search text in Tables and Data Browser persists across process kill via `@SceneStorage` (per-window on iPad)
-- iOS Settings: iCloud Sync toggle (off keeps connections, groups, and tags on this device only and disables the sync toolbar button), Rows per Page picker (50/100/200/500, applied to new data browser sessions), Default Safe Mode picker (applied when adding a new connection)
+- iOS Settings: iCloud Sync toggle (off keeps connections, groups, and tags on this device only and disables the sync toolbar button), Rows per Page picker (50/100/200/500, applied to new data browser sessions), Default Safe Mode picker (applied when adding a new connection), "Hide query in Live Activities" toggle that swaps the SQL preview for a generic "Running query" label on the lock screen and Dynamic Island
 - iOS: alert when the active connection is deleted mid-session (for example via iCloud sync from another device), so a stale screen no longer fails silently on the next action
 - iOS: Face ID, Touch ID, or Optic ID lock with cold-launch protection and idle timeout (1, 5, 15, or 60 minutes), opt-in from Settings
 - iOS: Connection Info tab replaces the per-connection Settings tab, showing host, SSL, SSH tunnel, active database, and live connection status
