fix(quality): keep rustdoc attached across multi-line attributes

[seonghobae]

Summary

scripts/check_docstrings.py only treated lines that start with #[ as attributes, so the continuation lines of a multi-line attribute (e.g. #[expect(clippy::missing_panics_doc, reason = "…")] formatted by rustfmt over four lines) reset its "documented" state and a properly documented public item was reported as public item lacks /// rustdoc. Observed on #372 (longitudinal_cwc_artifact.rs), worked around there by moving the attribute; this PR fixes the checker.

• Track bracket depth from the opening #[ so every attribute line up to the closing ] is transparent.
• New regression test_multi_line_attributes_do_not_detach_rustdoc: a documented pub fn behind a multi-line #[expect(...)] must pass, an undocumented pub struct behind a multi-line #[cfg_attr(...)] must still be reported at the right line.

Evidence (local, main-based)

• RED: the new test failed with 2 != 1 before the fix (documented item falsely reported).
• GREEN: python3 -m unittest tests.quality.test_check_docstrings 6/6; coverage report --fail-under=100 stays 100% (check_docstrings.py 55 stmts / 24 branches, TOTAL 1357 / 674); scripts/check_docstrings.py on the real tree PASS; validate_documentation.py PASS; git diff --check clean.
• Pre-existing, unrelated: test_hourly_workflow_schedule_credentials_and_queue_gate fails on main@a243f18d (owned by fix(actions): align central hourly admission contracts #492).

유효한 여러 줄 Rust 속성에 ]가 포함된 문자열이 있으면 문서화된 공개 항목이 문서 누락으로 잘못 보고될 수 있으므로, 병합 전에 속성 경계 인식을 수정해야 합니다.

문자열 내부의 대괄호를 속성 종료로 계산하지 마십시오.

Line 36은 문자열과 raw string 내부의 ]도 닫는 대괄호로 계산합니다. 예를 들어 #[expect(\n reason = \"]\",\n clippy::foo\n)]에서 reason 줄이 깊이를 0으로 만듭니다. 다음 속성 줄은 documented를 False로 재설정합니다. 그러면 문서화된 pub 항목을 누락으로 잘못 보고합니다.

속성 lexer가 문자열, raw string, 블록 주석 상태를 줄 간에 유지하게 하십시오. 구조적 [와 ]만 깊이에 반영하십시오. 이 입력을 포함하는 회귀 테스트도 추가하십시오.

검색된 학습에 따르면, 다중 줄 괄호 추적은 문자열과 주석 상태를 줄 간에 유지해야 합니다.
