🔄 Improve Connection Status Messages During Code Changes

[ahelme]

Problem

When making code changes to the extension, the Configuration panel immediately shows "Failed to connect" error messages, even though it's just a temporary cache clearing/reconnection issue.

Current Behavior

• Code change → Immediate "Failed to connect" error
• User sees error and thinks something is broken
• Connection actually works fine after brief delay

Expected Behavior

• Code change → "Retrying connection..." message
• Brief retry period with user-friendly status
• Only show "Failed to connect" after actual retry attempts fail

Implementation

• Update connection status messages to be more user-friendly
• Add retry indication before showing failure
• Distinguish between temporary reconnection vs actual connection failure

User Experience Impact

• Reduces user confusion during development
• More professional error messaging
• Clear distinction between temporary and permanent issues

Priority: Medium (UX improvement)
