fix(#1336): report exact physical line of too-wide line in multi-line comments

[yegor256]

Fixes #1336.

Summary

comment-is-too-wide.xsl used to report every offending line inside a multi-line comment with the comment block's own start @line, since the XSL had no way to compute the offset of a line within the tokenized comment text.

Now each defect's @line is computed as the comment's start @line plus that line's offset within the tokenized text (position() - 1), so the reported location points at the actual offending physical line instead of always the first line of the comment.

As part of this fix, the previously duplicated multi-line/single-line xsl:choose branches were merged into a single loop over the tokenized lines, since the offset computation subsumes both cases (a single-line comment simply has an offset of 0).

Changes

• src/main/resources/org/eolang/lints/comments/comment-is-too-wide.xsl: compute per-line offset and remove the resolved @todo puzzle.
• src/test/resources/org/eolang/lints/packs/single/comment-is-too-wide/catches-multiline-wide-comment.yaml: assert on line 2 (the actual offending line) instead of line 1.

Test plan

• mvn test -Dtest=LtByXslTest passes (463 tests, 0 failures) — includes all comment-is-too-wide fixtures plus structural checks (XSL @id checks, motive presence, schema validation).
• Verified via a scratch parse of the fixture input that XMIR represents a multi-line comment as a single <comment @line="N"> node containing real newlines, confirming the offset approach is correct.

🟡 Changes recommended

The updated XSL now feeds eo:defect-context(.) a tokenized string (not the original <comment> node) and bypasses the existing eo:lineno(@line) helper before doing arithmetic, which is inconsistent with established patterns and can reduce output quality/robustness when @line is absent or non-numeric.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Updates the comment-is-too-wide lint to report the physical line number of an offending too-wide line within multi-line comments, and aligns the related fixture to assert the new, precise location.

Changes:

• Compute defect/@line as comment @line + (position() - 1) while iterating tokenized comment lines.
• Remove the resolved @todo puzzle by restructuring into a single per-line loop.
• Update the multiline fixture to assert @line='2' (the actual offending line).

Thanks for the fix — the per-line offset calculation is a clean improvement over the previous single-line-only reporting, and all checks are green.

CI is fully green on this one, but GitHub reports the branch as no longer mergeable cleanly against master (merge conflicts need to be resolved). Since this also touches actual XSL logic rather than being a trivial change, I'm routing it to a human for a rebase/conflict resolution and a final look rather than merging as-is.

@yegor256 It is not a good idea to name Git branches the way you named this one: "claude/eager-planck-jocorp". You've earned -6 points. Next time, better give your branch the same name as the number of the ticket that you are solving. In this case, a perfect name, for example, would be "1338". Your running score is +1692; don't forget to check your Zerocracy account too).

CI is green but this PR now has a merge conflict with master (GitHub reports it as not mergeable/"dirty"). Needs a rebase before it can be merged.

CI is green here, but GitHub is reporting this branch as conflicted with master right now, so it can't be squash-merged as is. Requesting a look/rebase before merging.

This PR now has merge conflicts with master (likely from other recently merged fixes touching nearby files) and can't be merged as-is. Needs a rebase before it can go in.
