UPDATE PACKAGE WITHOUT USER UI CONFIG

This archive intentionally does NOT include:
- settings/ui_builder.json
- settings/ui_builder_draft.json
- settings/ui_builder_published.json
- settings/backups/*

Reason: these files contain the user's UI Builder layout, triggers, component shortcuts and global shortcut sequences. Extract this archive over an existing installation to update code without overwriting local UI/shortcut settings.

New fields are backward-compatible: UIBuilderManager normalizes existing JSON and supplies defaults for missing fields.

If installed into an empty directory, the application will create default empty UI Builder config files on first start.
