处理流程
----------
1. 读入文件，仅保留 \begin{document}…\end{document}（若无则全文）。
2. 先按 **空行 ``\n\n``** 粗分成若干 `raw_block`。
3. 对每个 `raw_block` 再用 ``LatexTextSplitter`` 细分为 `fine_blocks`：
- 校验：细分前后 ``count_dollar_signs`` 值必须一致，否则抛 `ValueError`。
4. 遍历 `fine_blocks`：
- 若区块 **不含 ``\begin``**，应用三条“删除多余 \\\\”规则（见 `_strip_linebreak_backslash`）。
5. 将处理后的 `fine_blocks` 用 ``\n\n`` 连接为 `txt` 并执行 6.1–6.4 后处理。
6. 写入最终 TXT，返回其绝对路径。
