Summary of Changes

Hello @lukhnos, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on refining the logging within the KeyHandler.mm file. It enhances the precision of an existing warning message and removes two redundant debug NSLog calls, contributing to a cleaner and more focused codebase by eliminating unnecessary output and improving diagnostic messages.

Highlights

• Logging Clarity: The NSLog warning message related to _grid being used after release has been updated for improved clarity, changing a generic 'used after release????' to a more specific 'warning: _grid used after release'.
• Debug Log Removal: Two debug NSLog statements, which were logging Preferences.allowMovingCursorWhenChoosingCandidates and input.inputText, have been removed from the _handleCandidateState: method, streamlining the code and reducing unnecessary output.

Code Review

This pull request cleans up some NSLog calls. The changes are good, especially removing the debug logs. I've also noticed a potential logic issue in setInputMode: where a nullptr _grid is not handled correctly, which could lead to a crash. I've added a suggestion to make the code more robust.
