fix(sqlserver): detect top-level pagination ordering

[HandSonic]

Summary

• Detect ORDER BY at the top SQL level with the T-SQL lexer before adding SQL Server OFFSET/FETCH pagination.
• Add the fallback ORDER BY (SELECT NULL) when ordering appears only inside a window expression, nested query, string literal, or comment.
• Preserve a real outer ORDER BY, including one split by a comment.

Validation

• SqlServerSqlBuilderTest regression coverage for window, nested query, string/comment, and outer-order cases.
• Fork CI: Backend tests and package, Frontend lint/test/build, repository checks, JavaScript CodeQL, Java CodeQL, SBOM, and license summary passed.

Latest-main verification (2026-09-04)

• Rebased onto 144a04ee2; full SQL Server plugin suite passed (83 tests).n- git diff --check` and pairwise integration analysis passed.

The lexer-based top-level detection correctly ignores nested queries, window clauses, strings, and comments while preserving a real outer clause. Focused tests cover the relevant regressions. Approved.

Superseded by a corrected review because shell quoting corrupted the submitted text.
