yaze/src/app/gui/canvas.cc
scawful f6f278bf65 Refactor OverworldEditor and Tile16Editor for enhanced functionality and user experience 
- Removed unnecessary build flags for Yaze minimal builds in release.yml.
- Updated version number to 0.3.2 in yaze.h to reflect recent changes.
- Enhanced OverworldEditor with new method to scroll the blockset canvas to the currently selected tile, improving navigation.
- Implemented logic to handle area size checks for ZSCustomOverworld v3, ensuring compatibility with different ROM versions.
- Refactored tile selection and drawing logic in Tile16Editor for improved accuracy and user interaction.
- Updated context menu in OverworldEditor to include a refresh option for map changes, enhancing usability.
