Prerequisites checklist

• I have read the contributing guidelines.

What is the purpose of this pull request?

This PR originated from #536. While working on that, I found the scope had become too large, so I split this refactoring into a separate PR.

In this PR, I've used the native getLocFromIndex method added in #376 instead of the custom findOffsets util.

Notable changes:

• Replace the findOffsets util with the native getLocFromIndex.
• Use the d flag and a named capturing group for the reversedPattern regex.
• Declare skipRanges as const and reset it with skipRanges.length = 0 to avoid creating a new reference each time.
• Consolidate three ESQuery selectors into a single selector.
