chore: bump version to 1.0.0 and update release metadata

Update package references from RC/preview versions to stable 1.0.* across all templates and project files. Mark RC1 roadmap as completed and update documentation to reflect v1.0.0 release. Add GestureManager cleanup in SkiaView.Dispose() to prevent memory leaks. Update copyright years to 2025-2026 and add development artifacts to .gitignore.
