Develop - Circle to search

[sameerasw]

This pull request introduces a new "Circle to Search" gesture feature, allowing users to trigger the Google "Circle to Search" action via a long-press gesture overlay or as a remappable button action. The implementation includes UI options, persistent settings, gesture handling, and system integration.

Feature: Circle to Search Gesture

• Added a persistent setting key circle_to_search_gesture_enabled to SettingsRepository to store user preference for enabling the gesture.
• Introduced UI toggle in OtherCustomizationsSettingsUI for enabling/disabling the "Circle to Search" gesture, which is only active if the gesture bar is hidden.
• Updated MainViewModel to manage the state of the new gesture setting and keep it in sync with preferences. [1] [2] [3]

Gesture Overlay Implementation

• Added OmniGestureOverlayHandler, a new class that displays an overlay for the gesture, handles long-press detection, and provides haptic feedback. The overlay is shown/hidden based on the relevant settings and device state.
• Integrated the overlay handler into ScreenOffAccessibilityService, including lifecycle management, configuration change handling, and reacting to preference changes. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Remappable Action Support

• Added "Circle to Search" as a remappable action in the button remap UI, and updated ButtonRemapHandler to support triggering the gesture (with haptic feedback) when this action is selected. [1] [2]

System Integration Utility

• Implemented OmniTriggerUtil, a utility for triggering the Google "Circle to Search" session using reflection and Shizuku, handling both root and non-root scenarios.
