This PR improves code health by replacing the deprecated var keyword with let or const in several JavaScript files.

🎯 What:

  • Replaced var with let or const in js/rendered-page-builder.js.
  • Replaced var with let or const in js/fallback-renderer.js.
  • Replaced var with let or const in js/history-manager.js.

💡 Why:
Using modern let and const declarations instead of var improves code maintainability and prevents issues related to variable hoisting and scope. It follows modern JavaScript best practices and enhances overall code readability.

Verification:

  • Syntactic validation was performed using node -c on all modified files.
  • Verified that all variable declarations were correctly converted while preserving CSS var() usages in strings.
  • Performed a recursive grep search for the var keyword in the js/ directory to ensure complete coverage.
  • Ephemeral log files and verification scripts were removed before submission.

Result:
The codebase now follows more modern JavaScript standards, making it more predictable and easier to maintain for future development.

I have replaced all occurrences of the deprecated `var` keyword with modern `let` or `const` declarations across `js/rendered-page-builder.js`, `js/fallback-renderer.js`, and `js/history-manager.js`. This improvement enhances code readability and maintainability by using block-scoped variables.

- Used `const` for variables that are not reassigned.
- Used `let` for variables that require reassignment (e.g., loop counters, results).
- Preserved CSS `var()` usages in `js/rendered-page-builder.js` and `js/saved-sections-manager.js`.
- Verified changes with `node -c` for syntax correctness.
- Confirmed the removal of `var` keywords throughout the modified files.

Replaced all occurrences of the deprecated `var` keyword with modern `let` or `const` declarations across `js/rendered-page-builder.js`, `js/fallback-renderer.js`, and `js/history-manager.js`. Also resolved merge conflicts by adopting optimized logic from main while ensuring it uses modern variable declarations.
