Refactor NewProjectDialog to use shared model

claude · claude · commit 4baddbab400b · 2025-11-18T00:40:34.000Z
Created NewProjectDialogModel with all business logic:
- GetMapsWithoutProjects(): Filters maps that don't have projects
- ValidateProjectName(): Checks name validity and uniqueness
- ValidateMapSize(): Validates even numbers for blank maps
- CreateProject(): Handles project creation for both map types
- ShouldShowSizeFields(): UI logic for showing/hiding fields

Refactored both Chili and RmlUi dialogs:
- Chili: 176 lines → 115 lines (35% reduction)
- RmlUi: 120 lines → 95 lines (21% reduction)

Both dialogs now use identical business logic:
- Same validation rules
- Same project creation flow
- Same map filtering
- Zero duplication

All dialog logic is now in the model, dialogs are pure UI.
