 This loop generates the "Features by IDE" comparison table:
 - Outer loop: Iterates through each feature from VS Code's feature list (using VS Code as the canonical source)
-- Inner loop: For each feature, iterates through all IDEs to check support in their latest version
+- Inner loop: For each feature, iterates through all IDEs to check support in their latest versions
   - Gets the latest version using ideEntry[1].versions | first
   - Looks up the support level for that feature in that version
   - Outputs ✓ (supported), P (preview), or ✗ (not supported)
