fix(body_patch): replace text in a table's holder and its cells in one edit

[airmang]

무엇

apply_body_ops의 replace_text는 찾은 글이 든 문단마다 편집 하나를 만들었다. 표를 담은 문단의 글과 그 표 칸 안 문단의
글이 함께 맞으면 두 편집 구간이 겹쳐, 바깥 문단 편집이 어긋난 위치에 붙고 저장 검사가 ValueError: malformed XML로
멈췄다(파일은 쓰지 않음).

이제 편집된 문단 안에 또 편집된 문단이 있으면 바깥 문단 하나로 묶어, 그 안의 치환과 칸의 lineWrap SQUEEZE→BREAK
편집을 한 번에 적용하고 전처럼 줄 배치 정보를 지운다. 겹치지 않는 경우의 결과는 전과 같다.

시험

• tests/test_body_patch.py::test_replace_text_in_a_table_holder_and_its_own_cell_at_once: 표를 담은 문단과 그 칸에서 같은
  글을 바꾸면 두 곳 모두 바뀌고, SQUEEZE 칸은 BREAK가 되고, 문서가 다시 열린다(고치기 전에는 malformed XML로 실패).

Exact head: 91cf300.

Reviewed paragraph/sublist span discovery, outermost edited paragraph grouping, reverse-ordered text/wrap splices, escaping, count refusal and layout-cache removal. Nested holder/cell edits are coalesced while disjoint edits retain their previous behavior. No unresolved code finding. All four local body-patch tests passed, including the new nested holder/cell save/reopen regression and untouched-cell SQUEEZE preservation.

All 13 current CI checks pass; verified successful workflow head SHA and read its test/lint/type/hygiene log (6,929 passed, 18 skipped, 1 xfailed; coverage 90.04%).

Merge held: after #505 merged, git merge-tree against current main 366e25d reproduces a content conflict in CHANGELOG.md. Preserve both entries when resolving against latest main, then revalidate the changed head and integration. No conflicted integration-test pass is claimed. COMMENT because this authenticated account owns the PR.

Re-reviewed exact head 622e256. Range-diff confirms only rebase/CHANGELOG placement changed from the previous review. Rechecked outermost edited paragraph grouping, nested holder/cell text and wrap splices, escaping/count refusal and selective SQUEEZE/cache handling. No unresolved finding; previous conflict is resolved.

All four local body-patch tests pass. All 13 current CI checks pass; verified workflow head SHA and read test/lint/type/hygiene logs (6,938 passed, 18 skipped, 1 xfailed; coverage 90.05%). Integrated latest main 6539e9e, including the independently merged #507, without conflicts; all 69 body-patch/HWP-open tests pass on tree 2f2761933366c367736b0824bebf538d82ec85c6. This validates the PR integration and does not claim resolution of #507's separate previously reported finding. Ready for expected-head-SHA squash merge. COMMENT because this account owns the PR.
