Fix welcome message visibility when background or other settings are changed

[Copilot]

Problem

The welcome message in the LearningMapEditor was only checking if there were no nodes or edges to determine visibility. This meant that even when users modified settings like the background color, title, or language, the welcome message would still appear on an empty canvas. This behavior was confusing and not future-proof for additional settings.

Solution

Introduced a new helper function isDefaultRoadmapData() that checks whether the roadmap is in its complete default state. The function evaluates:

• Whether there are no nodes or edges (excluding debug edges)
• Whether settings are at their default values (no custom title, language, or background modifications)

The welcome message now only appears when the roadmap data is truly in its default state, making the behavior consistent and predictable.

Changes

• Added isDefaultRoadmapData() helper function in helper.ts
• Updated LearningMapEditor to use the new helper function for determining welcome message visibility
• The solution is future-proof: new settings can be easily added to the default state check

Testing

// Before: welcome message would appear even with custom background
isDefaultRoadmapData([], [], { background: { color: "#ff0000" } })  // Now returns false

// After: welcome message only appears with default state
isDefaultRoadmapData([], [], { background: { color: "#ffffff" } })  // Returns true

This ensures users get a clean editing experience once they've made any customizations to their learning map.
