fix(fmt): correct peek_comment_between to scan comments within range

[Galoretka]

Motivation

The function used take_while with a range predicate starting from the first comment in the file. This stops iteration as soon as a comment before pos_lo is encountered, causing the function to almost always return None when earlier comments exist.
Lists relying on this check (e.g., commasep’s has_comments computation) could mis-detect “no comments between”, affecting line breaking and spacing decisions.

Solution

Replace the logic with skip_while(c.pos() <= pos_lo) + take_while(c.pos() < pos_hi) and find the first non-blank. This matches the intended semantics and aligns with has_comment_between’s filtering approach.

can you pls add a test with the issue this fixes? Thank you

looks AI generated, but also a legit bug/patch.
i'll try to come up with a repro myself if they don't answer

I will add tests if you don't mind

@Galoretka great, thanks!
i think that a unit test where u mock several cmnts will probably be easier to setup than finding an actual solidity repro, but do whatever u prefer
