🎨 UX IMPROVEMENTS

Button States

Default → [Purple Gradient] "Insert Context"

Loading → [Blue + Spinner] "Inserting..."
  ↓ Success
Success → [Green + Check] "Context Inserted ✓"
  ↓ 2 seconds
Default → [Purple Gradient] "Insert Context"

OR if error:
  ↓ Error
Error → [Red + X] "Failed to load"
  ↓ Show alert with troubleshooting
  ↓ 3 seconds
Default → [Purple Gradient] "Insert Context"

Error Messages

Before: "Failed to create context"
After: "Failed to create context: GitHub API rate limit exceeded. Try again in an hour, or use a different GitHub account."

Validation

Before: Save any URL
After:

1. Check URL format
2. Fetch URL
3. Validate HTTP 200
4. Check content not empty
5. Verify it's text not HTML
6. Then save
