editorial feedback

1. In spec language, comparisons don't result in a Boolean value. You have to say something like "If a < b, then let _result_ be *true*".
2. BigInts notation in spec text doesn't include the trailing n. 0n_ℤ should just be 0_ℤ.
3. Regarding "If currentYieldingValue equal to end, " and "if step is zero and start is not equal to end": use "is"/"is not" or "="/"≠" to compare values as defined in various editorial changes for comparisons ecma262#2877 (comment).
4. Use "Let ... be ..." and "Set ... to ...", never "Set ... be ...".
5. No need to introduce _iterator_ before returning it, just return the result of the AO call directly.
6. The URL in the note points to the wrong place. https://tc39.es/proposal-Number.range/playground.html should be https://tc39.es/proposal-iterator.range/playground.html.
7. I would rename option to something like optionsOrStep.
8. I don't like that ifIncrease is shadowed. It looks like you can just get rid of the outer binding.
9. Why can't you just inline CreateNumericRangeIterator into Iterator.range? I don't see any reason to do a type test, branch, and then completely defer to an AO.
10. CreateNumericRangeIterator doesn't seem to have its return type declared.
11. I don't think you need to introduce "NumericRangeIterator Object". What's the purpose?
12. "NOTE: Prevent value overflow." should be its own step, referring to the next/previous step, and include more explanation.

Use ecmarkup's --lint-spec and --strict options to catch some of these for you. Make sure you update to the latest version.

I introduce NumericRangeIterator because I expect there will be more types of range in the future, for example, Temporal/Date range and I hope they'll have different object types.

All other reviews are fixed. Thanks!
